Add UI button actions to send arbitrary OSC values.

[cubee-cb]

Just adds an action to buttons that sends a Float to an address over OSC. (e.g. to control a VRChat avatar, or some other OSC application)

I've just implemented it with OscType::Float for now since it can represent Float, Int, and Bool. (at least for VRChat)
Unsure if making separate actions for each type or trying to handle the type internally somehow (type: float or float_value: 3.5) is better. (in draft for feedback)

# button press example
click_down:
  - type: SendOSCFloat
    parameter: "/avatar/parameters/button1"
    value: 1
click_up:
  - type: SendOSCFloat
    parameter: "/avatar/parameters/button1"
    value: 0

It also merges the OSC client creation from openxr.rs and openvr.rs into state.rs state.app, and makes osc.rs send_params() take in a list of devices instead of app_state itself, since I was having borrow issues calling app.sender.send_params(overlays, app) (approximately).

Small note, setting a bool to 0 works as False, and setting it to 1 shows up as True in VRChat's OSC debug panel, but my avatar doesn't react to the True state. Not sure if I broke something on my avatar, or what. Needs some more testing.

Would also need to update documentation here:

i love the idea!

i'm not 100% happy with having a separate action per-type, and it's currently limited to one argument per parameter (so no vrchat chatbox messages, for example), but i'm not sure if i can do that without modifying something somewhere to make OscType serialisable.

ideally i want to use something like the following format:

    click_up:
      - type: SendOSC
        parameter: "/chatbox/input"
        arguments:
          - type: String # text to send
            value: "Test osc button"
          - type: Bool # send immediately
            value: true
          - type: Bool # play chatbox noise
            value: true

but, i'll mark this as ready if you're happy to merge this as-is.

edit: i came back and tried again with a "stepping-stone" enum for deserialisation that gets converted to the appropriate OscType when sending. much happier, but needs testing.

ok, after a brief test it seems to be working, and my avatar's issue of not detecting the True value is resolved now that it's actually a Bool. (perhaps was a vrchat bug...)
multiple values can be sent now, so now we can make quick-chat panels for vrchat's chatbox and such.

here's the testing buttons i used:
(i use a custom layout, these replaced my volume buttons)

  # OSC buttons
  - type: Button
    rect: [346, 50, 38, 38]
    corner_radius: 20
    font_size: 15
    fg_color: "#cad3f5"
    bg_color: "#006000"
    text: "Y"
    click_down:
      - type: SendOscValue
        parameter: "/avatar/parameters/hardware/headsetConnected"
        values:
          - type: Bool
            value: True
    right_down:
      - type: SendOscValue
        parameter: "/chatbox/input"
        values:
          - type: String # text to send
            value: "Test osc button"
          - type: Bool # send immediately
            value: True
          - type: Bool # play chatbox noise
            value: True
  - type: Button
    rect: [304, 50, 38, 38]
    corner_radius: 20
    font_size: 15
    fg_color: "#cad3f5"
    bg_color: "#600000"
    text: "N"
    click_down:
      - type: SendOscValue
        parameter: "/avatar/parameters/hardware/headsetConnected"
        values:
          - type: Bool
            value: False

did you do a cargo format on this? if not, please do

[galister]

looks good otherwise

cargo fmt?
