Replaced opamps with single quad-channel
...
Replacement has better specs and is not backordered. BOM price is also a
bit better.

Added ICSP Header/breakout to programmer
...
Also added secondary footprint for alternate TVS Diode
(ESD protection component) that's about 1/10th the cost
of the one currently used (suggested by the UART Bridge's
Datasheet.
