Implement the ability to configure and select an HRIR preset to use with the HRIR filter, or remove the preset. It will validate the file's usefulness before setting it for the player to use. Also, fixed back center channel filtering for 7.0 format audio. Signed-off-by: Christopher Snowhill <kode54@gmail.com>
