This adds a couple things seen while trying to release to npm
Basically takes a lightweight approach to what is in @GMOD/bam
1) It does not run the build step during yarn publish, so now preversion: runs yarn build
2) It does a clean using rimraf
3) It does clean with prebuild step
4) With postversion it pushes back to github, also what is in @gmod/bam
