Refactor TTMLParser.js:TTMLParser.parse

[MichielCuijpers]

I've selected TTMLParser.js:TTMLParser.parse for refactoring, which is a unit of 225 lines of code and 50 branch points. Addressing this will make our codebase more maintainable and improve Better Code Hub's Write Simple Units of Code guideline rating! 👍

Here's the gist of this guideline:

• Definition 📖
  Limit the number of branch points (if, for, while, etc.) per unit to 4.
• Why❓
  Keeping the number of branch points low makes units easier to modify and test.
• How 🔧
  Split complex units with a high number of branch points into smaller and simpler ones.
