[Python] How to add custom extractor to yt-dlp?

I want to make a custom extractor for https://www.buzzsprout.com in order to extract season and episode numbers in addition to what generic extractor already does.

This is my script saved at: /usr/lib/python3/dist-packages/yt_dlp/extractor/buzz.py

from yt_dlp.extractor.common import InfoExtractor
import re

class BuzzSproutIE(InfoExtractor):
IE_NAME = 'buzzsprout'
_VALID_URL = r'https://www.buzzsprout.com/.*/(?P<id>[^/?#&]+)$'

def _real_extract(self, url):
video_id = self._match_id(url)
webpage = self._download_webpage(url, video_id)

# Extract the season number.
season = self._search_regex(
r'<span class="whitespace-nowrap">Season (\d+)</span>',
webpage,
'season',
fatal=False
)
# Extract the episode number.
episode = self._search_regex(
r'<span class="whitespace-nowrap">Episode (\d+)</span>',
webpage,
'episode',
fatal=False
)

return {
'id': video_id,
'title': self._html_search_regex(r'<title>([^<]+)</title>', webpage, 'title'),
'season': season,
'episode': episode,
}



And I have added this line to /usr/lib/python3/dist-packages/yt_dlp/extractor/_extractors.py:

from .buzz import BuzzSproutIE


But yt-dlp --list-extractors | grep -i buzz still doesn't show my extractor and https://www.buzzsprout.com urls are still handled by generic extractor.

What am I missing?
