Split up Project into its executables

[Blackjacx]

This project contains executables that each can run on different platforms. Distributing them in one opackage has the following disadvantages:

• platform the whole package is restricted to the lowest common denominator (macOS)
• downloading and building the whole package takes much more time than building a single executable
• not all executables need all package dependencies

🚨 When this is done don't forget to update the Bitrise screenshot step for Beiwagen!
