BBC seems to have two URLs for their radio programmes
https://www.bbc.co.uk/programmes/[id]
and
https://www.bbc.co.uk/sounds/play/[id]
Example
https://www.bbc.co.uk/programmes/m0002d1w
https://www.bbc.co.uk/sounds/play/m0002d1w

Right now the latter gives an error in Youtube-dl, I think it should be forwarded to the former automatically
Thank you for consideration!

Basically, this only requires an update of the URI regex:

diff --git a/youtube_dl/extractor/bbc.py b/youtube_dl/extractor/bbc.py

(No, I am not creating a PR, because it means I need to add a test, re-run all existing tests, fix existing tests, figure out how to test tests which require a login and may have been broken. And investigate, whether the added regex is sufficient, or should be more general or specific. This is just a hint at what needs to be fixed in the most simple case. ;-))
