Re-releasing with workaround for some calibration glitches - seems to be issue with MicroPython Timers.

With many improvements made to the code, including better calibration and the features of the Rev1 PCB, it's time to bundle up a release. All features are now controlled via the UI Menu, with settings stored at the top of libs/config.py. If you don't have a display you can edit this directly to change settings.

Testing with the stock XTAL shows that it is really only good for short term/testing, as it is too temperature sensitive. I have replaced this with a TCXO on a few boards, and validating/testing those will be the main focus for now.

Rev-1.0

The initial release, the code now seems stable and sync's well to other devices. The main.py code is designed to work with the WaveShare Pico-OLED-1.3 display, but can be adapted for others.

Calibration of the XTAL will still be an issue, as the stock Pico is built with a passive XTAL (rather than a TCXO - temperature compensated module). It is possible the replace the XTAL, this will be investigated to see the performance benefits.

For now my focus is shifting to building the PCB and validating that.
