[MTR4] Moszyan Railways Resources for MTR

Fixed the Class 730 Aventra not showing up due to a json mistake (unless you had Soodari's original pack installed funny enough) Also added the new ✨ livery for the 730

Removed some resources that are in other packs, which included the Dutch PIDS from the World PIDS Pack for some reason.

Fixed the pack to include the new Metrocar door sounds

Changed version numbering to match original UCR releases. Adds a bunch of trains and sounds, and fixes some textures.
