Breaking changes in v4.0.0

The introduction of several standard libc math functions causes a behavior change of the existing fmod() function...

• rename fmod() => mod() to align w/ GLSL counterpart
• add new fmod() w/ standard libc behavior (same as JS % op)
• add remainder() w/ standard libc behavior

Installation
