Feature request : Support more indexers

First of all, thanks for this great tool !

Many other trackers allow music uploads, and some of them are also based on gazelle, with very similar API schema. Only to name a few : GGn, LzTr, DiC. Others are not based on Gazelle but still allow music uploads.

So it would be quite nice to be able to cross-seed music to those trackers as well !

This would introduce the potential for requiring matching, given that I'm not entirely sure how those trackers would standardize naming across the board - which is something currently relied on with the RED/OPs functionality.
