[PATCH v2 0/2] MR7493: mp3dmod: Implement an IMFTransform interface.

[Brendan McGrath (＠redmcg)]

This MR adds the IMFTransform interface to the mp3dmod module so that it can be used as an MFT.

It also calls `MFTRegister` (so the MFT can be found via `MFTEnum`) and also registers a byte stream handler for the mp3 format.
