Remove explicit progressbar dependency and inherit from bioformats2raw

[melissalinkert]

This should allow picking up the update in glencoesoftware/bioformats2raw#309.

Not assigning reviewers yet, just opening so I don't forget to do this. Propose the following plan:

• get bioformats2raw 0.12.0 tagged (when we're ready)
• get the rest of 0.10.0 here merged (again, when we're ready)
• bump to bioformats2raw 0.12.0 here
• then test this PR to make sure that progress bars are working as expected per the discussion in Update progressbar to 0.10.2 bioformats2raw#309, merge, and tag 0.10.0
