ModuleNotFoundError: No module named libadobe

Bug description

Same repro steps as in: https://github.com/Leseratte10/acsm-calibre-plugin/issues/72. Seems like https://github.com/Leseratte10/acsm-calibre-plugin/pull/88 perhaps didn't fix it for MacOS. I'm using the default sed.

I cloned the repo from master (commit 27bd9531c44f9896e4ade81c768c12e393e51e9a).

I get this error:

Lots of errors, though I suspect some are expected since this is meant to be portable across multiple OSes.

Okay installing DeDRM first made was what I needed to do to make this work. Unfortunately it doesn't work, if I import an acsm file it stays an acsm file, but that's separate to this issue.

For this issue it'd be nice if there was a more comprehensive README + better error messages.

[Leseratte10]

Installing DeDRM is not needed for this plugin to function in general. I suspect a Calibre restart or computer restart might have solved this particular problem.

During the bundling, it fails to compile the keyextract code since you don't have the proper compiler installed, but that should't stop the plugin from functioning since it's only needed on Linux anyways, not on Windows or MacOS.

If the plugin fails to turn ACSM files into EPUBs, there's another error so you'll need to run Calibre in debug mode and check the logs again (or post them here).

I know the error handling for the plugin isn't always the greatest, most of the issues come from the fact that the plugin needs to load 3rd-party python plugins (which almost no other Calibre plugin does) and that doesn't always work properly.
