Update with aht10 library

Added aht10 library inline

All examples compile: I removed the cortex team examples for now as compiling those is more tedious

More demos compile

Neopixel demo now compiles

make more examples compile

Make aht10 example compile (even though path seems wrong)

Moved main from every branch into the main repository

Rename examples into cortex-team examples. I plan to make every separate example contain its own main file

Force size optimization by default - lots of packages are too big for a cortex m0

Fix link for stm32: should be m0 not m1

Initial version: blinky
