Improve Module specification

[yiliansource]

Is your feature request related to a problem? Please describe. Adding new modules to emitters is a bit janky, and there are a lot of cluttered module files that basically all do the same.

Describe the solution you'd like Instead of having a lot of module classes that function similarly, we could generate modules through a builder, where users can, through chaining, specify the driven property, the value and what it's driven by (lifetime/size).

Example

new ModuleBuilder()
    .drive("size")
    .by((t) => t * 2)
    .through("lifetime")
    .build();

Implemented using the proposed example.

Additionally, module builders can use the relative() chain to apply the value relative to the original value.
