altoslib: Fix accel value flipping for TM v3.0

TM v3.0 uses the same log file format value as TM v2.0 but has a
different accelerometer, which requires a different function for
inverting the raw values. Detect v2.0 devices and use the old function
for them while using the new function for all others.
