Use pattern for indicating timestamp in filename for pbp-meta-gen

As part of our discussion earlier today:

In regards to the current --prefix PREFIX option for pbp-meta-gen, maybe, alternatively, consider something like

--pattern PATTERN

to indicate how pbp-meta-gen can extract the timestamp from the input filenames?

PATTERN would be any string with fragments that collectively indicate the timestamp like:

• {YYYYMMDD} : 4-digit year, 2-dig month, 2-digit day
• {YYYY} : 4-digit year
• {YY} : 2-digit year
• {MM} : 2-digit month
• etc.

Where the possible symbols inside a {} fragment include Y, M, D, H, m, s ..

The NRS11 case would be something like --pattern NRS11_{YYYYMMDD}_{HHmmss}.flac

Just an idea.

Good idea @carueda. This may be a beneficial approach.
