Patch for ITkPixV2 segfault case, + updated error messages in Rd53b/ItkpixV2 DataProcessors
Fix for issue seen in #269. Additions in this MR:
- Fix for segfault seen there
- Add @okovanda's fix to Rd53b as it seems to apply there as well, along with this same patch
- Add basic test case which catches this segfault in the base SW, using specific block patterns (will update to randomized patterns later)
- Add chip ID to logging output for Rd53b and ItkpixV2 DataProcessors
