Subject: [PATCH] fix(nbt): unwrap single-element arrays in CRN BlockReader NBT
 parsing
 (Station[1]/RealTimeStation[1]/ScheduledStation[1]/StationInfo[1]/Train[1])
 to get real TrainName/Destination/StationName/Platform; fallback destination
 to precise StationName code (e.g. CE-03 2) when Destination is invalid or is
 CRN aggregated tag name. Bump to v1.0.74
