Need support for ogg in "Media"

[bit4man]

Describe the enhancement

If you try to upload a "ogg" formatted audio file to "media" you get an error saying:

Source: components/media_source/local_source.py:124
integration: Media Source ([documentation](https://www.home-assistant.io/integrations/media_source), [issues](https://github.com/home-assistant/core/issues?q=is%3Aissue+is%3Aopen+label%3A%22integration%3A+media_source%22))

I suggest adding ogg to allow for fully open codecs to be used by Home Assistant, now that Voice assistants and other features have made their inroad to Home Assistant proper. 

### Use cases

Most of my media library uses OGG and not MP3/MP4. It's a very old and well maintained open source alternative to proprietary mp3 and similar codecs. 

### Visual examples

### Anything else?

Clearly not all codecs can be default. Perhaps having the ability to add a list of codecs used by a given install is the best solution.
