Address BEP031 macro requests

[tsalo]

Changes proposed:

• Add an optional parameter to schema.make_filename_template, n_dupes_to_combine, that determines the number of suffixes or extensions that should be combined into <suffix> or <extension>, respectively, when the filename pattern otherwise matches.
• Refactor utils.combine_extensions to only combine extensions of compressed versions (for example, nii.gz and nii will combine to form nii[.gz], but ome.tif and ome would not combine).

The Microscopy imaging data template:

sub-<label>/
    [ses-<label>/]
        micr/
            sub-<label>[_ses-<label>]_sample-<label>[_acq-<label>][_stain-<label>][_run-<index>][_chunk-<index>]_<suffix>.<extension>
            sub-<label>[_ses-<label>]_sample-<label>[_acq-<label>][_stain-<label>][_run-<index>][_chunk-<index>]_<suffix>.json

The photo one:

sub-<label>/
    [ses-<label>/]
        micr/
            sub-<label>[_ses-<label>]_sample-<label>[_acq-<label>]_photo.<extension>

Thank you @tsalo!
For BEP031, the new n_dupes_to_combine works perfectly for extensions. I will also be able to drop the long suffix list in the macro.
I tested without the n_dupes_to_combine as well, and .ome.tif is rendered correctly.

I don't know if there are other cases where the number of dupes to combine would be different for suffixes and extensions? For BEP031, this is not an issue.
Thanks!

I can see that coming up in the future, but I don't think we need it yet.

Thanks for your comments. I'll merge then.
