Add RF_SIM sub-protocol to SLT-protocol

[arildlangseid]

I recently got a Radiomaster TX16S with the 4in1 module.

When trying to use the SLT protocol with my SLT-dongle which was included in my RealFlight 7.5 box, I could easily bind and use the 8 channels to fly. But after crash I was unable to use the momentary switch on my transmitter to reset the model.

This pull request adds a new sub-protocol to the SLT-protocol to send 10 channels to the RealFlight SLT-dongle. Pilots can now assign the momentary switch to ch9 and setup RealFlight to reset new model from transmitter.

Edit: Thanks to MRC3742 that pointet out that even though my SLT-dongle was in my RF 7.5 box, you can not assign the reset-button to ch9/ch10 in RF7.5. RF8 supports reset model via ch9/ch10. RF8 is the latest version I have used.

It looks great. Thanks!

All changes are ok.

I was able to download the current main branch and successfully update my internal module to 1.3.4.18

I can now see all ten channels working in the RealFlight 7.5 channel monitor using the SLT wireless dongle supplied with this simulator version. (although the calibration screen only shows eight channels)

Unfortunately i cannot find a way for RealFlight 7.5 to allow the reset function to be assigned to a channel? Therefore I believe a minimum of Realflight 8 or above would seem to be needed to use this function?

Thanks for the additional channels hidden on this dongle - Rich

Hi, I found my RF7.5 CD and installed on an old computer - and yes I can confirm that the options to set model reset is missing in RF7.5 (upgraded to 7.50.015) and you need RF8 to reset your model via the SLT-dongle.

Thanks - and a big thanks to all contributors to both OpenTX/EdgeTX and Multiprotocol-TX-Module!
