Use the custom soundset system and start with High Elf Footman since it is not too big.

Update to https://www.hiveworkshop.com/threads/getmainselectedunit.325337/#post-3597445 so it supports savegames.

The system should provide sound sets and let them be shared between unit types and units:

function AddUnitSoundSet takes string filePrefix returns integer
function EnableUnitSoundSetForUnitType takes integer unitTypeId, integer unitSoundSet returns nothing
function DisableUnitSoundSetForUnitType takes integer unitTypeId, integer unitSoundSet returns nothing
function GetUnitSOundSetForUnitType takes integer unitTypeId returns integer
function EnableUnitSoundSetForUnit takes unit whichUnit integer unitSoundSet returns nothing
function DisableUnitSoundSetForUnit takes  unit whichUnit, integer unitSoundSet returns nothing
function GetUnitSoundSetForUnit takes unit whichUnit returns integer

Support BlzGetUnitSkin.
