trackma crashes when trying to parse local library with anitopy

[y0shir]

I have switched to "experimental" parser in hopes that it would detect episodes that normal couldn't. But now it crashes when I try to launch it. Here is readout:

AttributeError: 'Engine' object has no attribute 'parser_class'

Changing "title_parser": "anitopy", to "title_parser": "aie", in config fixed it. I know that it's experimental, but I didn't think it would crash everything.
I'm using pip version with on debian trixie.

You need to install the anitopy Python library.

Trackma already falls back to aie automatically if it can't import anitopy - implemented in the commit cb19ddb. You won't see this if you're using the stable version though, maybe we should publish another release.
