Bad Extensions: Incorrectly suggests .webm extension for Matroska (.mkv) files not encoded using VP8/VP9

[RogueScholar]

As stated in the title, Czkawka is incorrectly asserting that some .mkv files should have a .webm file extension. WEBM is a subset of MKV in that they use the same container format, but WEBM files also have the added restriction that they can only employ either the VP8 and VP9 codecs in the constituent video streams and Ogg or Vorbis for the audio ones. Most standalone media players are fairly lenient these days, but this should be addressed as soon as possible because it does break playback for these files in web browsers and anything else that more strictly conforms to the WEBM specification.
