Changing the size of a struct by accident lead to random the wrong data from the eeprom and can screw the eeprom up pretty bad. Better bail out if the eeprom size changes and let the developer make that an intentional choice. The template magic is there to print out the actual and expected size:
/Users/arne/oss/opentx/radio/src/datastructs.h:1045:3: error: static_assert failed "struct size changed"
static_assert(expectedSize == realSize, "struct size changed");

CHKSIZE(TrainerData, 168);
Reuse some of the DSM2 routines to avoid code duplication.
This first version only implements the protocol on the Taranis. (and not
Telemetry code is currently untested and will not work (Polarity mismatch). The main protocols to use telemetry are FrSky protocols and not a high priority on the Taranis.
Patch v3: Fix myeeprom.h, include option value in menu.
Patch v4: Fix identing, name substructs of modeldata
the code is a bit more complicated since unions can have structs or simple types. Also change Telemetry sensor to be a struct, since a class with all public is identical to a struct in C++
