CompatHelper: bump compat for MIMEs to 1, (keep existing compat)

[github-actions]

This pull request changes the compat entry for the MIMEs package from 0.1 to 0.1, 1.
This keeps the compat entries for earlier versions.

Note: I have not tested your package with this new compat entry.
It is your responsibility to make sure that your package tests pass before you merge this pull request.
