Change subject: sysmocom_sja2: Implement EF_CHV files using construct
......................................................................
sysmocom_sja2: Implement EF_CHV files using construct
this has the advantage of getting the encoder for free (so far we only
had the decoder). While at it, also add some tests data for the unit
tests.
