Retrosonic

* Rerendered older sounds using the 96kbps bitrate, as its supposed to be, instead of the old standard which was 160kbps, this consequentially reduces the pack size.

* fixed a horrid issue with "brushing_gravel4.ogg" which contained all 4 sounds in a single file for whatever reason.

* removed the legacy folders, also reduces file size, can still be accessed through older versions.

* Added custom step sounds for horses, as the vanilla ones have modern stone sounds in their composition.

* Updated cherry leaves sounds.

* Removed reverb from explosion sounds. (delay/echo effect is still there)

* Brushing gravel and sand sounds changed slightly to make the actual gravel/sand sounds more noticeable.

* Placing calcite now emits the break sound as intended (i forgot)
