LR1121 - Adds FEC to 2.4GHz FSK (#2832)

LR1121 - Adds FEC to 2.4GHz FSK (#2832)

* initial working FSK

* reduced sync word and 100hz settings

* 2.4 and SubG 1000Hz and D500 test modes

* small FSK tweaks

* testing K1000 F Low

* bring back lora modes and other cleanup

* update OTA time and TLM ratio

* remove extra ClearIrqStatus and move ignoreSecondIRQ

* add back 200Hz Full Low

* fuck this shit off!

* cleanup GetPacketStatus

* ENUM ALL THE THINGS! and clean up the modes

* add extra Radio.isFirstRxIrq to loop

HWtimerCallbackTock does not run when disconnected, so this is never reset while waiting for a connection.

* Revert "add extra Radio.isFirstRxIrq to loop"

This reverts commit 1353a026bc625c24c9ccba5639cfcc7dcda623f2.

* remove reliance on isFirstRxIrq

There is enough time to call GetIrqStatus for the second radio.

* check DIO1 before calling IsrCallback()

If the second radio packet has already been check, no need to call the IsrCallback and GetIrqStatus.

* remove LR1121 PACKET_TO_TOCK_SLACK

* why read 4B when 3B will do

* make unit test happy

* adds unique sync word for packet filtering

* UID[6]... SMH

* change hops to be inline with F1000 rates

* syncSpamAmountAfterRateChange

* syncSpamAmountAfterRateChange

* remove mav_ul

* cleanup

* change rx to PROTOCOL_MAVLINK if mav packets are received

* add back NonceFHSSresult condition

* fix config call from startCWTest

* lowercase variables

* use lib_ignore

* change bitrate to use a 10000 multiplier

* Hamming(7,4) FEC

* Fix Lua after rebase

* add FEC lib

* cleanup debug and comments

* commenting

* revert DK500 back to DVDA

* fix unit tests
