Draft: Misc GEM event builder bugfixes
WIP
[Based on top of !131 (merged).]
This MR aims to improve the GEM event builder against corrupted events sent by the VFAT. In particular, it should prevent breaking the event building when the VFAT misses a small number (<18) of BC0.
It will lead to a new, backward compatible, data format revision, v302b
.
