Update reincore_MegaGrit.jsfx to v2.0 (#418)

 - Fixed a critical bug where the mid-band signal was always silent.
 - Added 'Envelope Smoothness' slider for direct control over the modulation's character.
 - Replaced the high-band clipper with a smoother soft-clip distortion.
 - Added input clamping for improved stability at high gain.
 - Lowered the default 'Input Drive' for a better experience.
 * Special thanks to ashcat_lt for the feedback!
