Tyler Goodlet e5e70a6011 Extend `Flume` methods
Add some (untested) data slicing util methods for mapping time ranges to
source data indices:
- `.get_index()` which maps a single input epoch time to an equiv array
  (int) index.
- add `slice_from_time()` which returns a view of the shm data from an
  input epoch range presuming the underlying struct array contains
  a `'time'` field with epoch stamps.
- `.view_data()` which slices out the "in view" data according to the
  current state of the passed in `pg.PlotItem`'s view box.

Tyler Goodlet 125e31dbf3 Implement by-type tick-framing in throttler loop
This has been an outstanding idea for a while and changes the framing
format of tick events into a `dict[str, list[dict]]` wherein for each
tick "type" (eg. 'bid', 'ask', 'trade', 'asize'..etc) we create an FIFO
ordered `list` of events (data) and then pack this table into each
(throttled) send. This gives an additional implied downsample reduction
(in terms of iteration on the consumer side) from `N` tick-events to
a (max) `T` tick-types presuming the rx side only needs the latest tick
event.

Drop the `types: set` and adjust clearing event test to use the new
`ticks_by_type` map's keys.

Tyler Goodlet 715e693564 Improved clearing-tick-burst-oriented throttling
Instead of uniformly distributing the msg send rate for a given
aggregate subscription, choose to be more bursty around clearing ticks
so as to avoid saturating the consumer with L1 book updates and vs.
delivering real trade data as-fast-as-possible.

Presuming the consumer is in the "UI land of slow" (eg. modern display
frame rates) such an approach serves more useful for seeing "material
changes" in the market as-bursty-as-possible (i.e. more short lived fast
changes in last clearing price vs. many slower changes in the bid-ask
spread queues). Such an approach also lends better to multi-feed
overlays which in aggregate tend to scale linearly with the number of
feeds/overlays; centralization of bursty arrival rates allows for
a higher overall throttle rate if used cleverly with framing.

Tyler Goodlet b89fd9652c `binance`: always request an extra 1min OHLC bar
Seems that by default their history indexing rounds down/back to the
previous time step, so make sure we add a minute inside `Client.bars()`
when the `end_dt=None`, indicating "get the latest bar". Add
a breakpoint block that should trigger whenever the latest bar vs. the
latest epoch time is mismatched; we'll remove this after some testing
verifying the history bars issue is resolved.

Further this drops the legacy `backfill_bars()` endpoint which has been
deprecated and unused for a while.

Tyler Goodlet 7ef8111381 Provide `datetime`-sorted clears table iteration
Likely pertains to helping with stuff in issues #345 and #373 and just
generally is handy to have when processing ledgers / clearing event
tables.

Adds the following helper methods:
- `iter_by_dt()` to iter-sort an arbitrary `Transaction`-like table of
  clear entries.
- `Position.iter_clears()` as a convenience wrapper for the above.

Tyler Goodlet 94290c7d8b `kraken`: ignore mismatched zero-ed pps (for now)
See more details in the GH comment:
https://github.com/pikers/piker/issues/373#issuecomment-1380988581

More or less we need to pull and include the transfer fees for
withdrawals in our ledger tracking but this serves as a sloppy
workaround for the moment.

Tyler Goodlet d2aee00a56 `kraken`: only do unsub if connected
Trying to send a message in the `NoBsWs.fixture()` exit when the ws is
not currently disconnected causes a double `._stack.close()` call which
will corrupt `trio`'s coro stack. Instead only do the unsub if we detect
the ws is still up.

Also drops the legacy `backfill_bars()` module endpoint.

Tyler Goodlet 28fd795280 Only require `-b <brokername>` for filtering
Instead of requiring any `-b` try to import all built-in broker backend
python modules by default and only load those detected from the input symbol
list's fqsn values. In other words the `piker chart` cmd can be run sin
`-b` now and that flag is only required if you only want to load
a subset of the built-ins or are trying to load a specific
not-yet-builtin backend.

Tyler Goodlet 2a158aea2c Rework `_FeedsBus` subscriptions mgmt using `set`
Allows using `set` ops for subscription management and guarantees no
duplicates per `brokerd` actor. New API is simpler for dynamic
pause/resume changes per `Feed`:
- `_FeedsBus.add_subs()`, `.get_subs()`, `.remove_subs()` all accept multi-sub
  `set` inputs.
- `Feed.pause()` / `.resume()` encapsulates management of *only* sending
  a msg on each unique underlying IPC msg stream.

Use new api in sampler task.

Tyler Goodlet 326f153a47 Catch overruns on throttled feed subs too
Previously we would only detect overruns and drop subscriptions on
non-throttled feed subs, however you can get the same issue with
a wrapping throttler task:
- the intermediate mem chan can be blocked either by the throttler task
  being too slow, in which case we still want to warn about it
- the stream's IPC channel actually breaks and we still want to drop
  the connection and subscription so it doesn't be come a source of
  stale backpressure.

Tyler Goodlet f5cd63ad35 Ensure correct stream is set on each `Flume`
Set each quote-stream by matching the provider for each `Flume` and thus
results in some flumes mapping to the same (multiplexed) stream.
Monkey-patch the equivalent `tractor.MsgStream._ctx: tractor.Context` on
each broadcast-receiver subscription to allow use by feed bus methods as
well as other internals which need to reference IPC channel/portal info.

Start a `_FeedsBus` subscription management API:
- add `.get_subs()` which returns the list of tuples registered for the
  given key (normally the fqsn).
- add `.remove_sub()` which allows removing by key and tuple value and
  provides encapsulation for sampler task(s) which deal with dropped
  connections/subscribers.
