Minor improvements and fixes.

test/nbt_helpers: add a headline to output
Build system: remove comma from array that I added bc I thought it was correct sytax, it wasn't
lib/cli: change argument order of PositionalArgument constructor to fit in with Flag and UnpositionalArgument
lib/cli: properly define what is private and what is public in the ArgumentsParser class
