Rethink the archive database

[clemgoyens]

.... add extra fields in archive databse , e.g., flags binary number.... to be checked

[pdevis]

For archive and metadata db, make nested tables, so that there is much less repetition remove sequence path?

also anomaly database:

• add processing time
• make sure angles etc work

[pdevis]

also need to fix system_id for L0

[pdevis]

Consider whether this can be structured by periods (where during a period the same metadata is used)
