Reworking Dockerfile, CI, NPM Scripts

[Kawanaao]

In this pull request I want to change the scripts for development, debugging and publishing, for now the goal is

• Caching
• Rewriting Circle CI for new Dockerfiles
• Adding generalized scripts to NPM, including content generators (Halfway with generators)
• Adding Github Workflows files or at least integration with Circle CI, for PR validation
