The idea of adding that block was to have the ability to remove transcodes. I'll create another PR to solve that issue.

Gitlab lint

Run formatters in tests folder

Fix template

Run formatters

Fix mimetype when the URL has params

Wrap transcode HTML in transcode block

Extract transcodes to reusable function

Fix copies

Using Cloud Storage could generate urls like:

`https://storage.googleapis.com/<BUCKET_NAME>/<PATH>/testwebm?Expires=1612931745&GoogleAccessId=<ACCOUNT>&Signature=<SIGNATURE>`

Passing parameters to the URL returns None in mime.guess_type(url)

Also, extracting the mimetype to some property that can be reused. Similar to https://github.com/wagtail/wagtail/blob/master/wagtail/documents/models.py#L170

Fixes #56 proper call to paginator

Migrations fix

Tracks

Conditionally show some things only if modeladmin is installed, addded links for editing/adding tracks
