Some places have left placeholders for items/formats that will be implemented in
the future. Also one bigger part will be arcs in zone polygons instead
of "pure" positions (check RoyalBlue54L-Feather board)

testing

Refactored and corrected the parsing of floats and ints, addressing edge cases and ensuring consistent behavior across the codebase.
Added option to run tests on private schematics and boards without
explicitly saving the testdata in the project.
