MarkItDown resets the warning filter

[AdrianVollmer]

Hey, i think this is an amazing project!

I started to use markitdown in one of my projects and suddenly I got tons of warnings. I suspect it's because of this line:

markitdown/packages/markitdown/src/markitdown/converters/_mp3_converter.py

Line 23 in dbdf2c0

resetwarnings()

According to the docs, catch_warning is not thread safe. I'm using markitdown in threads. Besides, I'm not sure why resetwarnings() is called at all. A lot of my dependencies probably have warning filters set, and this line disables them all.

Can we remove the finally clause or perform this check differently please? Thanks in advance!

Thanks for the report. Yes, I should get rid of this part of the code. I'm making some other, relatively large, changes to converters and I'll see if I can remove this for the next release.
