saugns v0.4.8b. Value range modulation for more parameters. For consistency, allow "Modulation with value ranges" for every parameter which accepts value sweeps. That's all with modulators, except the main phase & PM parameter `p` and its frequency-scaled PM subparameter `p.f`, where range-mapping doesn't make sense. This means it's now supported for `c` (channel mixing) and for self-PM `p.a` as well.
