rbxl format: possible content types?

[jmkd3v]

It looks like Roblox sometimes uses the content type rbx-format/avatar_meshpart_accessory when downloading rbxl format data from avatar accessory assets, like the Hat asset type. It might be worth documenting this for later.

Studio also uses the application/x-roblox-studio media type when copying instances to the clipboard.
