Add columns to error messages

[NoahGJAC]

Just caught up to the latest video in the series and saw @orosmatthew wanted to but didn't implement columns. This series has been great in teaching me C++ and learn more about how compilers work.

Simple solution to add a column count to error messages that works pretty well for it's simplicity.

Changes:

• Parser.hpp
  • Update to display column count in error_expected() and the binding.
• Tokenization.hpp
  • Add a column_count int that is incremented on each consume and is reset to 1 on new lines.
  • Update all token.push_backs() to include column_count
