the boss, `conf.toml`

[goodboy]

i'm thinking we might as well have a top level config file for users to choose and tweak a lot of optional/variable settings we starting to acquire.

Some options i can think of off-hand,

[allocation.default]
size_units = 'currency'
limit = 5e3
slots = 4

[allocation.options]
size_units = 'units'
limit = 10
slots = 1

[allocation.peeneez]
size_units = 'percent_of_port'
limit = 20
slots = 6

[style]
colorscheme = 'default'

[tractor]
port = 6116

[ui]
update_throttle = 60  # Hz

opinions welcome obvsly.

TODO:

• support write-triggers-UI-update
  • probably we can use watchfiles by the pydantic author:
    • https://github.com/samuelcolvin/watchfiles
    • most notable is the awatch api: https://watchfiles.helpmanual.io/api/watch/#watchfiles.awatch
    • should get similar functionality as from alacritty, namely dynamic config reloading on file writes
    • for font size auto-scaling, we need to handle DPI changes
      when a window gets moved to a diff display:
      https://github.com/pikers/piker/pull/523/files#r1237362101
• font size and style settings
  • added in get font style from main config #523 which apparently makes it all work on windows as
    well B)
  • relatedly supporting using the traditional ctl +/- to
    grow or shrink the font size and subsequently resize all UI
    widget sizes around the changes.
    • note many of our custom widgets in particular already have
      api facilities for this, we just need some kind of std
      interface and kb handler to trigger it all

A version of this actually already landed in #489 and is being added to in both #486 and #523 🏄🏼

Oh and we ended up jsut going with conf.toml for filename.
