Use pygfried in file format identification

[sevein]

This commit simplifies file format identification. It removes all file
identification related models and data entries from the fpr application.
Instead, it defaults to pygfried, a Python package that makes siegfried
available as a CPython extension.

pygfried only reports PRONOM identifiers for the time being but the plan
is to support additional registries.

What's left is fpr.fp{rule,tool,command}, that we could eventually move
out of the database into an interoperable format easier to manage externally.

Connects to #55.

This looks great @sevein and the way you integrated siegfried is very cool.

The only thing that got my attention is that the switch from using the job print helpers to the logger stops creating the %SIPLogsDirectory%fileFormatIdentification.log file. If we start moving in that direction maybe we should update workflow.json to not have those references anymore.

Thank you, I totally forgot about that!
