The Twilight Forest sound fixes

Included in Eclectic Sounds, check it out!

Most likely from an oversight, a lot of entity sounds from Twilight Forest are mono instead of stereo, which can completely annihilate any perception of positional audio.

Because of this, some sounds like bird singing or crow just get overshadowed by random noises that shouldn't be possible to be heard, like hearing a deer sound as if it's close to the player, but it is in fact 2 chunks away.

For a clearer understanding, you can listen to the short video below.

Note: Some mobs do need to be mono, like cicadas and deer, so I tried to only touch what needed to be arranged. I don't add or remove any sounds from the base mod.
