Beat707 Mikro Updates

I just updated the Beat707 Mikro files, including HEX files for the ATmega328 ICs, some Docs and better folder names for the sources.

Also, if you could support me on Patreon, I will them continue to release more Open Source Arduino compatible stuff. ;-) I have hopes of creating a simple sample-player synth with wavesequencing. Maybe using the Arduino DUE or even going into a Bare-Metal Raspberry PI mode.
