Wasmercowic

A new version with many cowtastic features, most importantly compatibility w/ SwiftWasm.

• it properly uses Swift 5 for compilation, when available
• it now uses Swift's .random function, when available (instead of importing arch specific versions)
• now includes a vaca CLI tool

What a cowsy day ...

The Noze.io cows module as a standalone Swift Package Manager package (also included Xcode dylib build as well as makefiles for Linux w/o SPM).

Rock solid 1.0.0 release. Moo!
