Tyler Goodlet e91a50a1ba Make `get_cached_feed()` an asynccontextmanager
Adjust feed locking around internal manager `yields` to make this work.

Also, change quote publisher to deliver a list of quotes for each
retrieved batch. This was actually broken for option streaming since
each quote was being overwritten due to a common `key` value for all
expiries. Asjust the `packetizer` function accordingly to work for
both options and stocks.

Tyler Goodlet 2514843fc1 Port to the new `@tractor.msg.pub` decorator API
The pub-sub data feed system was factored into `tractor` as an
experimental api / subsystem. Move to using that which greatly
simplifies the data feed architecture.

Tyler Goodlet 22670afe58 Generalize the publisher/fan-out system
Start working toward a more general (on-demand) pub-sub system which
can be brought into ``tractor``. Right now this just means making
the code in the `fan_out_to_ctxs()` less specific but, eventually
I think this function should be coupled with a decorator and shipped
as a standard "message pattern".

Additionally,
- try out making `BrokerFeed` a `@dataclass`
- strip out all the `trio.Event` / uneeded nursery / extra task crap
  from `start_quote_stream()`

Tyler Goodlet 72f417b9c2 Support monitor linked symbol selection
This allows for using a monitor to select the current option chain
symbol!

The deats:
- start a bg task which streams the monitor selected symbol
- dynamically repopulate expiry buttons on a newly published symbol
- move static widget creation into a chain method to avoid multiple
  quotes requests at startup
- rename a bunch of methods

Tyler Goodlet 1866dd1812 Fix for adjusted contracts subscription bug
If quotes are pushed using the adjusted contract symbol (i.e. with
trailing '-1' suffix) the subscriber won't receive them under the
normal symbol. The logic was wrong for determining whether to add
a suffix (was failing for any symbol with an exchange suffix)
which was causing normal data feed subscriptions to fail to match
in every case.

I did some testing of the `optionsIds` parameter to the option quote
endpoint and found that it limits you to 100 symbols so it's not
practical for real-time "all-strike"" chain updating; we have to stick
to filters for now. The only real downside of this is that it seems
multiple filters across multiple symbols is quite latent. I need to
toy with it more to be sure it's not something slow on the client side.
Oh, and store option contract to ids in a `dict` for now as we may want
to try the `optionsIds` thing again down the road as I coordinate with
the QT tech team.

Tyler Goodlet 07eb8ae5e0 Use binary search (bisection) to sort table rows
This is an optimization to improve performance when the UI is fed real
time data. Instead of resorting all rows on every quote update, only
re-render when the sort key appears in the quote data, and further, only
resort rows which are changed using bisection based widget insertion to
avoid having `kivy` re-add widgets (and thus re-render graphics) more
often than absolutely necessary.

Tyler Goodlet 9e4786e62f Initial dynamic option chain UI draft
There's still a ton to polish (and some bugs to fix) but this is a first
working draft of a real-time option chain!

Insights and todos:
- `kivy` widgets need to be cached and reused (eg. rows, cells, etc.)
  for speed since it seems creating new ones constantly is quite taxing
  on the CPU
- the chain will tear down and re-setup the option data feed stream each
  time a different contract expiry button set is clicked
- there's still some weird bug with row highlighting where it seems rows
  added from a new expiry set (which weren't previously rendered) aren't
  being highlighted reliably

Tyler Goodlet 8647216b75 Tabular kivy UI improvements
`Row`:
- `no_cell`: support a list of keys for which no cells will be created
- allow passing in a `cell_type` at instantiation

`TickerTable`:
- keep track of rendered rows via a private `_rendered` set
- don't create rows inside `append_row()` expect caller to do it
- never render already rendered widgets in `render_rows()`

Miscellaneous:
- generalize `update_quotes()` to not be tied to specific quote fields
  and allow passing in a quote `formatter()` func
- don't bother creating a nursery block until necessary in main
- more commenting
