TODO: Implement Single-Pass RTF Tokenizer

The current, temporary solution in https://github.com/Draemondor/T-Notes/commit/183e0e5a4787b5ca73baab68eae51b606f187edc for the RTF file parser is to utilize a quick hack found on stack overflow to strip the plain text from the file, and create a TXT file. From there, we can parse the TXT
file as normal. This is very inefficient. I don't recommend that we keep this temporary hack.

This issue serves as a TODO reminder for myself to sit down and write the single-pass RTF tokenizer so that the job can be done right.
