Originally created and tested using LC-45GD4U and LC-45GX6U
Modified for LC-52D92U, removing PIP, adding more input discretes, etc.

Discrete on/off and input select 1-7 have all been tested

Sharp uses multiple device #s to control this unit, so this
device upgrade is built using Sharp Combo (Official) protocol.
The device #s are listed in "byte2"
Some keymap versions incorrectly(?) calculate EFCs in combo protocol, so
ignore them, or switch to using "Sharp" protocol to see what they should be.

Discrete "select input"s 1-7 are mapped onto shifted Num 1-7.
Use "Channel up" to simulate input select from "tuner" (see shifted Num 0)

For a non-extended 15-2117 (15-2116) you need to press "P" twice to
"shift" or the remote will assume you want to send an EFC.

Redundant "select input 1-4" and "surround" are listed for completeness
Reduntant codes *might* work better on some (untested) similar models.
