@GjjvdBurg kind nudge to get this moving

Will check the PR tomorrow again. I abstracted some code but the build seems to be failing; local epub files are pushed to the remarkable with the integrated code.

Same tests pass on the main @GjjvdBurg ✨

Hi @cvanelteren, thanks for making the changes, I think it looks good! The build is failing on formatting errors, do you have a chance to fix those? Also, it would be great if we could have a unit test that verifies epub functionality. I'm wondering if there are any good sources for that, maybe something like Project Gutenberg? That could imply adding a provider for it though, which does increase the scope of this PR so we could also merge this after fixing the formatting errors and then add that provider/test later

Will look into it no worries.

Thanks for adding the test @cvanelteren! Unfortunately the change to the PdfUrl provider causes the existing test_pdfurl_1 and test_pdfurl_2 tests to fail. It may help to run the unit tests locally to confirm

@GjjvdBurg did check it beforehand but lazily only checked what I added. There was a typo in the check. There are some other tests that fail relating to filenames that changed but I believe that is outside the scope of this PR.
