Saving TIFF image raises Value error

[jrief]

On attempt to save an image of type TIFF PIL raises a ValueError complaining with: "quality setting only supported for 'jpeg' compression".

This can easily be prevented removing the quality key from the options dictionary.

I already prepared a patch for this issue.

Unfortunately I introduced a regression in version 2.8.4. I tried to revert this, but now running the unit tests fails. This presumably is because GitHub changed something in their action scripts. Please check the "Install dependencies" section in those two jobs

what's the difference?

Therefore I'd like to propose to replace tox by GitHub's own matrix runner. I do that in all of my projects, and in my opinion that's a better approach.

What do you think?

Problem is in setup.py on this line: https://github.com/SmileyChris/easy-thumbnails/blob/c75a28152044f4f9cf3245d0acaa58a2c76ad4a3/setup.py#L25

Previous version imported get_version from https://github.com/SmileyChris/easy-thumbnails/blob/c75a28152044f4f9cf3245d0acaa58a2c76ad4a3/easy_thumbnails/__init__.py#L4

But now is imported file easy_thumbnails/get_version.py as module instead of function. Either get_version function should be renamed to something unique like get_package_version or module get_version should be renamed to prevent name conflict.
