Suggested Feature: Spread Spectrum Enable/Disable

[dtbradio]

Great library! That you were able to include as much functionality as you did with as small a footprint is amazing! I have one suggestion for a feature to add, and that is the ability to enable or disable the spread spectrum feature. I know that feature is implemented in the 1.4.X version of Adafruit's library, but your library is much better and I'd love to see that feature added.
