[Enhancement] Run code generators from the command lline

[Booklordofthedings]

Being able to run the code generators from the commandline would further both automation and also linux support. It also seems like a generally useful thing to have if the cli wants to offer comparable functionality to the IDE.

Im not sure what a good api for it would be, maybe something along the lines of BeefBuild -generate GeneratorName ConfigFile.toml where the toml file could contain the options in a key, value format. Otherwise the options for the generator could also be passed in via the cli directly.
