Bosch BME280 / Embedded Adventures MOD-1022 breakout

OK, it's all working, sort of...

Couple of the values coming back are suspect but I need to go through each function and check each one to ensure it's doing the right thing. I suspect it is just some rounding issues or other gotchas going from C to JS.

Some output from my test rig:

More when I've had time to work the functions and improve the code a bit. But still happy for anyone to chip in with improvement ideas.

Cheers
