// GetPathFromMediaMetadata validates and constructs the on-disk path to the media
// based on its origin and mediaID
// If a mediaID is too short, which could happen for other homeserver implementations,
// place it into a short-id subdirectory of the origin directory
// If the mediaID is long enough, we split it into pieces, creating up to 2 subdirectories
// for more manageable browsing and use the remainder as the file name. For example, if
// mediaID is 'qwerty', we create subdirectories 'q', 'w' within 'q' and place the file
// in 'q/w' calling it 'erty'. If the mediaID is shorter than 3 characters, the last
// character is the file name and the preceding character, if any, is a subdirectory name.
// based on its Base64Hash
// If the Base64Hash is long enough, we split it into pieces, creating up to 2 subdirectories
// for more manageable browsing and use the remainder as the file name.
// For example, if Base64Hash is 'qwerty', the path will be 'q/w/erty'.
