Add run loop for runtime

- Add send instruction to send the rgb values to the strip (since setting them and sending them is bs)
- Remove sending behaviour from rgb registers

 - changing the state register results in turning the strip on/off
-- changing the r/g/b registers results in changing the color
+- the rcr, rcg and rcb registers store the rgb value of the strip
 - the rgd register is the default register for storing data
 - the rgp register stores a pointer to "memory" space
 - the rgi register stores the input for operations that require two input values
