- Refactored the escape sequence parsing, and handling.

  It now uses a struct to store the escape sequence.

  Before it handles the escape sequence, it parses it,
  which includes things like getting any arguments
  that are supplied, and getting the mode type.

- Moved the code that handles control codes to a
  separate function.

The reason for doing this was because I wanted to make
the escape sequence handling faster, but also make the
code more readable at the same time.

I got the idea to do this from st, a terminal emulator
created by the suckless.org project.
