Add additional ensemble filename patterns

[jfrost-mo]

Based on Stephen's regexes in overlays:
http://fcm1/projects/roses_mi/browser/b/c/6/0/6/trunk/oemplotlib/oemplotlib/config.conf?rev=167053#L25

Also need to handle duplicate member numbers, such as in Global. This might be renumbering, or something else.

Under /net/home/h02/frhl/CSET/CSET, I tried running cset bake input.pp test.nc first_recipe.yaml
where my first_recipe.yaml is copy/paste from https://metoffice.github.io/CSET/reference/recipe-format.html and was aiming to point to a 'random' K-Scale .pp output file. My input.pp is a soft-link to a file somewhere else, but on first reading I got similar issue with filename reading. Looks like maybe there are some default assumptions on filenames currently?? My trying to specify filename format in the recipe didn't do much.

t would be good to be able to read in filenames with wildcards for dates to grab several files (* or [1-3]?))

[jfrost-mo]

It is already possible to use a wildcard (*) for getting multiple files, though I don't think this is documented in the read operator.

The only thing that is a little bit tricky is that if using the CLI you have to quote the filename to prevent it expanding in the shell. This isn't a problem is using the workflow however.
