Suunto EON Steel: add transmitter battery state reporting

Browse Source 
I'm not sure how reliable it is, and older wireless tank pods had a bug
in the reporting (looks like the battery voltage range calibration was
done incorrectly, and it reports 0% battery for new batteries).

But depending on how well it actually works when the batteries start
getting weak, the transmitter battery reporting is potentially *very*
useful.
