* #748 - Implement methods for processing various media types and preparing them for upload

* Various tweaks following code review:
- added blurhash generation
- changed thumbnails to jpeg
- throwing if file size cannot be retrieved
- move MediaProvider files to separate folder so they can cleanly be imported in the NSE
- added audio file processing
- switched all image resizing methods to ImageIO
- various renames

* Fix blurhash formatting issues, `swift-format-ignore-file` doesn't work

* Processing all media within unique folders to avoid conflicts

* Fix various warnings

* Rename `sizeForItemAt(_ url: URL)` to `sizeForItem(at url: URL)`

* Remove unnecessary resizeImage(UIImage) method, start by copying not moving the file to the unique location

* Add back warning for roomDetails.avatarURL
