MutantKoto, Mukoco & Macomate updated

Mutagene has updated MutantKoto to v0.9.9, Mukoco to v0.6.1 and Macomate 88 to v0.9.3.

MutantKoto v0.9.9 changes:

• Fixed fractional delay (timbre was previously dark for high registers, sometimes unstable for high "cutoff").

Mukoco v0.6.1 changes:

• Fixed fractional delay.

Macomate v0.9.3 changes:

• Fixed a bug in the fractional delays; all combs are now stable for "bright" and "decay" up to and equal to 1 (max).
• Comb filters tuned to the higher registers are also much clearer now.
• Somewhat optimized compared to previous version (estimate around 30% reduced CPU load).
