encapsulate Devices, add Frame glasses audio support

[OkGoDoIt]

Implements #532

Currently only supports audio, will add photos soon.

This affects a lot of files due to re-implementing the way devices are handled. The new device.dart is a base class for all possible devices, with the Friend and Frame being implemented as BtleDevice.dart. Eventually there may be other devices that are not btle.

This is my first contribution and also I'm new to Flutter, so please help me test this thoroughly.

Was able to connect and the frame shows "listening"

Wasn't able to test transcription as I'm having troubles myself with installing backend

I think it's probably good and I believe you should keep going and try add images as well

That screenshot is usually what it shows when it pairs to the frame but then disconnects either because the frame has been turned off or gone out of range. When I’m there tonight we can go over the scenario that led to that and figure out how to solve it.

There is also a potential issue if your frame has an old version of the firmware. Right now the only way to update the frame firmware is through the official Noa app, so let’s check that as well. I can add some firmware version checks on my end to improve the experience there as well.

@OkGoDoIt can you please resolve the conflicts? The issue Nik mentioned is resolved on the main branch. Also can you please share a demo working video of Frame with the Omi App? Thanks

Well it was difficult but I got photos and audio working simultaneously from the Frame! 😎 Still some code cleanup that I need to finish but this is major progress. Also there's a bunch of merges I need to do too. I will get to these Thursday.

@OkGoDoIt can you resolvle conflicts and once done we will merge today?
