John Corrigan 8d4d967341 add zip_attachment to EpubExport 
fixes CNVS-24178

- Updates FilesConverter so that it returns both files that will be
  displayed in the ePub and the files that are unsupported.
- Adds CC::Exporters::Epub::FilesDirectory class, which accepts a
  collection of file objects and adds them to a zip file.
- Updates UI so that a separate download link is present for the zip of
  unsupported files.
- Adds support to MIME::Types library to be able identify ePubs.
- Updates EpubExport to have many attachments; one epub & one zip.
- Updates process of creating attachments related to EpubExports so that
  the content_type value is properly set.

test plan:
- Have a course that contains files that are not supported by ePub, such
  as pdf, doc or xls.
- Navigate to `/epub_exports`.
- Click the button to generate an ePub for the given course.
- Observe that, after the successful generation of the course, two
  download links appear: one for the ePub, one for additional files.
