Some yt-dlp arguments such as allowed_extractors are expected to be a list.

However, the code in catt that parses -y only supports boolean or plain strings:

I can think of two alternatives to improve on this:

• hardcoding a few parameter names, such as allowed_extractors
• having an heuristic, so if the argument value starts with [ and ends with ] the text inside is assumed to be a list

Then if the value is deemed to be a list, it is parsed as such by splitting on commas.
