Output column names (CLI+docs) + ergonomics of matchprintf

[ross-spencer]

I might be missing something, but right now, the only documentation we have of column names output by FIDO is:

fido/fido/fido.py

Lines 803 to 804 in 33789ab

	parser.add_argument('-matchprintf', metavar='FORMATSTRING', default=None, help='format string (Python style) to use on match. See nomatchprintf, README.txt.')
	parser.add_argument('-nomatchprintf', metavar='FORMATSTRING', default=None, help='format string (Python style) to use if no match. See README.txt')

Previously I am guessing it was in the KB wiki: https://github.com/openpreserve/fido?tab=readme-ov-file#installation but I believe a long-term issue exists where this can't be accessed any more.

In terms of features, I wonder if a user friendly set of columns could be output? (if this can't be output already), i.e. CSV header.

We could also add this to the docs.

I can see looking around one or two folks use matchprintf, e.g. fido -matchprintf "%(info.mimetype)s,%(info.time)s,%(info.puid)s\n" filename to truncate data in rows. It's quite complex to setup though, I wonder if there's a way the ergonomics of this can be improved? (or if there already exists a conf file that might help take some of the pain away on every invocation)?

Lots of questions sorry! (I think I've had to work this out a few times in the past but haven't committed to writing an issue before now and should have saved my previous notes).

Thanks for reporting this @ross-spencer . FIDO will receive some TLC in the last quarter of this year/first of next. Will take a look at this issue then.
