Add Support for Using LIRC Devices as IR Towers (Based on the RCX-IR Project)

[mesheets]

Add support for using a LIRC-supported device as an IR tower. The project RCX-IR provides support for interfacing with LIRC-supported devices, but these capabilities have not been integrated with the IR tools.

Currently, IR tools support serial, USB, and TCP (virtual IR) devices. This would add LIRC as a supported target.
