NOTE:  This project/branch is not actively maintained.  I inadvertantly fried (at least) the final amp on my RS-HFIQ, and so until I can figure out how to repair that, I am not actively working on my Quisk branch.

Things that this code is intended to do:
- Provide control of the RS-HFIQ hardware (note, originally derived from other code; attribution in source).
- Provide a built-in iambic keyer with low latency, derived from the N1GP keyer.  Use Raspberry Pi GPIO.
- Provide hardware keying (vs. serial keying) of the RS-HFIQ using the front panel connector (intended for min latency CW).
- Provide some additional UI elements (adjust keyer, adjust power, etc).
