Recompute MET name hash in standalone code if not available
Recompute MET name hash in standalone code if not available. This is done in TP converters in Athena but in standalone code it needs to be done elsewhere.
The proposal is to recompute on demand (standalone only as Athena is fine). For this I made the updateHash
const
and the hash mutable
. It is protected by mutex.
