Xtce combined (IMAP-Science-Operations-Center#654)

* MNT: Update telemetry generator to iterate over all packet definitions

- Add a polynomial calibrator for analog conversions

- Add logic for variable length BYTES

Some instruments don't provide the apId column, so we can calculate
it ourselves. We do need the integer apid for the XTCE file.
