Add functions to change sound effect parameters

[StrixG]

This pull request adds functions to manipulate the parameters of sound effects. These functions doesn't work with the player voice at the moment.

bool setSoundEffectParameter(element sound, string effectName, string effectParam, var value)

Issue #320

[qaisjp]

Looks good so far! Thank you so much for this PR. 🎉

[ghost]

@StrixG Do you want to work more on this PR? I think it looks good enough.

[StrixG]

Yes. I can't figure out how to make this work for the player voice.

[dmi7ry]

Yes. I can't figure out how to make this work for the player voice.

Do you think it is possible? I thought voice uses different library (not BASS)

[qaisjp]

I believe voice is recorded via BASS and then encoded (for transmission) using Opus.

[qaisjp]

No, we don't use BASS for recording. According to #895 we use portaudio.

There seems to be some issue with reverb, but I doubt it's from your side.
Test resource SoundEffectsTest.zip

[Pirulax]

LGTM.

Looks good, tested lightly and seems to be working fine 👍

[patrikjuvonen]

@StrixG All ready? Let's merge this, please create a new issue for the player voice part and create the Wiki pages. Thank you!

Apologies for the long wait.
