Add support for adjusting the mark between slot time #25

Right now we send bytes as fast as we can - the mark time between slots is 0.

@nightrune says for crappy fixtures, sometimes you need to increase the time. The standard can go up to 1s (Designation 9, Table 6, E1.11)

Apparently 44uS from end-of-the-second-stop-bit to start-of-the-start-bit is considered 'slow DMX'. That's 88uS byte to byte

RDM changes the max time to 2ms. Be careful when implementing this that the max packet time isn't exceeded.
