First (untested) draft remote annotation ctl API
Since we can and want to eventually allow remote control of pretty much all UIs, this drafts out a new `.ui._remote_ctl` module with a new `@tractor.context` called `remote_annotate()` which simply starts a msg loop which allows for (eventual) initial control of a `SelectRect` through IPC msgs. Remote controller impl deats: - make `._display.graphics_update_loop()` set a `._remote_ctl._dss: dict` for all chart actor-global `DisplayState` instances which can then be controlled from the `remote_annotate()` handler task. - also stash any remote client controller `tractor.Context` handles in a module var for broadband IPC cancellation on any display loop shutdown. - draft a further global map to track graphics object instances since likely we'll want to support remote mutation where the client can use the `id(obj): int` key as an IPC handle/uuid. - just draft out a client-side `@acm` for now: `open_annots_client()` to be filled out in up coming commits. UI component tweaks in support of the above: - change/add `SelectRect.set_view_pos()` and `.set_scene_pos()` to allow specifying the rect coords in either of the scene or viewbox domains. - use these new apis in the interaction loop. - add a `SelectRect.add_to_view()` to avoid having annotation client code knowing "how" a graphics obj needs to be added and can instead just pass only the target `ChartView` during init. - drop all the status label updates from the display loop since they don't really work all the time, and probably it's not a feature we want to keep in the longer term (over just console output and/or using the status bar for simpler "current state / mkt" infos). - allows a bit of simplification of `.ui._fsp` method APIs to not pass around status (bar) callbacks as well!distribute_dis
