Automate Release Workflow

[madmalik]

I would like to automate the release workflow.

• display configured version number and release date for verification
• generate font files (ttf, otf and woff) from ufo export (fontforge?)
• generate zip file for download
• maybe: update font files for website (git update branch)
• maybe: update glyphs list on website
• maybe: update downloads links on website and readme
• maybe: create pull request for homebew-cask-fonts (brew bump-cask-pr)
• maybe: generate a second download with dotted zero as default (as suggested by @effinsky)
