[SX1276] getDataRate() no longer available

[matthias-bs]

Hi,

I just noticed that getDataRate() is no longer available for the SX1276 module.
No big deal - I can do without it, I was just surprised because the change was not mentioned in the RadioLib v7.6.0 Release Notes.

Best regards
Matthias

Indeed, I have decided to remove it - it doesn't really add much to most users, and if they really need to measure this, it can be easily implemented in the user code. To be fair it is mentioned in the release notes, though I agree it is kind of cryptic and not really highlighted - it should be more clear now. I also didn't want to raise the major version number just because of this (fairly small) breaking change.
