Support for Arduino platforms

[arengarajan99]

This program adds configurations for 32 bit and Microsecond Support for Arduino Only (can be extended universally by defining target configuration). Requires a little under 60kB worth of flash storage at the moment (Will not work for Nano and Uno boards as presently constructed). Blink program works out of the box.

Did you mean to include changes to the reactor-cpp submodule as part of this PR?

Looks good! Provided some feedback.

Looks like this needs a bit more fine tuning. Also, you've accidentally updated the reactor-ts submodule as part of this PR.

Forgot to hit the Finish your review button a while ago. Apologies! Here is some dangling feedback.
