(This is called "Activity" in Gadgetbridge, since we have that on the Bip, we should probably rename that to Workout also for consistency with the menus)
NOTE:
- Needs latest firmware
- Setting to Japanese or Korean leads to empty menus on the device. When
reconnecting you, will get a sceen which telling you to update. I highly
suspect it requires flashing Mili_wuhan.ft.kj (kj=korean,japanese)
- Rename MiBand2Service to HuamiService
- Move preferences around (Mi Band 2 has its own device specific settings now)
- Fix Cor menu items not syncing immediately in settings
- Try to support settings menu items on Mi Band 3 (buggy, disabled code for now)
This also improves firmware/RES probing to distinguish Mi Band 2/3 firmware files and Mi Band 3/Bip RES files.
Notes:
- Firmware flashing should might but is untested
- This basicall runs off the Amazfit Bip code which will probably incorrect (Mi Band 3 is proabably something between the Bip and the Mi Band 2)
