Add optional oversampling to stock plugins

Currently there is at least according to my personal measurements no or too little oversampling implemented in all non linear stock plugins in studio one, which makes them unusable to me. It is sad, that they sound muddier than they have to and I don't like to run my sessions at 192kHz just for that reason.

Namely the red light distortion, the bitcrusher, the fat channel and possibly the saturation mixer channel.

Please do not implement the oversampling like it was done for the pro eq (high quality mode), because this smears transients too much. To my own surprise oversampling seems to work very well in Ampire/the pedalboard and the Mai Tai Oscillators. So maybe there is some code already that just needs to be copied.

If possible different quality levels of oversampling might be nice, but a 4x option on everything would probably be fine as well.

Additional feature request for implementing oversampling:

A drop down menu in the plug to select oversampling amount: Off, 2x, 4x, 8x, 16x

Additional options:

Set (selected oversampling) for all of the same plugin within the session

Set selected oversampling as default

"Set selected oversampling as default" would be good for loading sessions and starting recording. Set selected oversampling for other plugins within the session would be great for mixing and for increasing oversampling quickly before mixdown/printing.

From what I can tell, there have been both aliasing and intermodulation distortion issues. Most plugins that have harmonics have this some anyways, but I feel like many presonus plugins have sounded too muddy for me to use. From what I've seen, 4x oversampling with the steep low pass can work well for mild saturation (maybe -60 to -45db harmonics). I've needed 8x to 16x to preserve clarity when heavily distorting. Current, a lot of presonus harmonics sounded to me to greatly loose clarity above 12khz when fully distorting.
