C Api: SoundEffects are missing setMix and setMixModulator

The LUA api includes:

playdate.sound.twopolefilter:setMix(level)
playdate.sound.twopolefilter:setMixMod(signal)

In addition to frequency and resonance. However the C API only includes the last 2: Inside Playdate with C

The same appears true for all of the SoundEffect types, such as RingModulator, Bitcrusher, etc.

Nevermind, in the C Api they are on the SoundEffect itself, and I forgot that.
