Beta & Bugfix branch.

Beta Builds/Bugfix branch

Please don't just install this unless you are prepared for frequent updates and potentially things breaking.

Now that FlashCGM is published I'm starting an unpublished branch for continued work. The GAM link for it is https://gam.fitbit.com/gallery/clock/e56ff2d7-5836-429c-a10c-10b1bb42dc54.

If you want to contribute feedback on it the usual link or in the Fitbit Discord server is the place.

Things different from current public release.

Main screen BG readings are now color coded to match the reading, matching the graph. This has allowed removal of the BG color theme settings simplifying things.
Alert mute buttons are now either 4 hours or 30 min. The current options were too noisy for several people dealing with a persistent high as an example. 4 hours should be sane.
Messaging code between watch and companion has been re-worked. Poll for settings info and data are separated and watch will keep asking for settings until it gets them before it will ask for data. Some users who use mmol/L as their units would have display in mg/dL if the poll didn't work. Messaging reliability also seems better now especially with the new Ionic/Versa firmware.
Colors tweaked a bit. The green was VERY hard to view in bright environments (the dots mostly) so moved to fitbit named colors which are brighter.

Everything above this line is being rolled into the public branch release ASAP due to.....

Messed up on the units check for mg/dl users. I made an assumption about the label the various API endpoints would use and I was wrong.
