Known issue: Bluetooth connection on linux + some info

[micimize]

Thought I'd open an issue to track the known BT issues on linux as well as report some findings while trying to troubleshoot in case they are helpful.

My hunch is that it's all downstream of some generic bluetooth/device permissions issue that results in the "unsupported" result in the first place, may investigate more later. But anyhow:

1. running /home/mjr/Downloads/Bazecor-1.4.0-rc.3-x64.AppImage I see:

   libva error: vaGetDriverNameByIndex() failed with unknown libva error, driver_name = (null)
   someone asked for accessibility linux
   hid configuration hid { isMainFrame: false, securityOrigin: 'file:///' }
   Filtered list
   [
     {
       deviceId: '/sys/devices/virtual/misc/uhid/0005:35EF:0012.001A',
       name: 'Defy BLE - 1',
       productId: 18,
       serialNumber: 'e5:86:2f:ad:9a:00',
       vendorId: 13807
     }
   ]

2. I go into the console and see the device is detected but not supported, so I try just clobbering the value with a breakpoint
   
3. Things start to load but don't really get past "Loading from neuron" (or something like that).
4. I see some repeated errors about opening the device:
5. and then a version error of some kind

Tried looking into some permissions a bit ie: https://unix.stackexchange.com/questions/96106/bluetooth-le-scan-as-non-root. No dice though.

Other misc issue while plugged in via USB is that I couldn't save layers due to split not being present on undefined or some such. Didn't investigate thoroughly though - I can always use my macbook when needed so these aren't existential issues to Bazecor for me personally.
