PoC of bike computer components

This release include:

• Support for waveshare 2in9 e-ink V1
• Basic support for e-ink in V2
• PoC and MVPs:
  • Recording the activity to FIT file
  • Reading and controlling the hardware
  • Partition management
  • Architecture design relying on the event dispatcher, and pub/sub pattern (that should be described somewhere eventually)
  • Auto-generated GUI
  • All main areas to make full blown bike computer are already touched (only BT left), now it's only a matter of developing the fundamentals further to add more, and more features.

Here's the demo what this release can do:

Next releases will:

• Drop the support for waveshare e-ink (in favor to Sharp MIP display), that may be a breaking change, so this release may be think as a 'checkpoint'. Idea for e-ink is too good to be abandoned completely, so if some new decent model will appear on the market, I will not hesitate to try it!
• Update the GUI, and fonts, probably add the custom graphics
• Add support to the BT to transfer FIT files
• Add unit and functional tests (about the time!)
• Add accelerometer HW
