feat: added TXT parser

[Totto16]

• I added support for the TXT sentence formatter (according to this)
• It supports multi and single sentences (see test cases)
• I added tests for it.
• I tested it on real hardware (with added TXT Parser #40)

This is related to #40

Sorry for the long standing PR. After a bigger refactoring your great PR did not fit anymore. And I also did not like the optional passing of the instance to the static method. I built on your PR an own implementation and thank you a lot anyway for your work! Hope everything works fine on your site with the new gps.js version

Thanks, if this PR at least helped to build a TXT parser I am totally fine with it, this is open source, so no need to apologize for long waits 😉

I haven't tested it yet, but if I find some error I'll report it 😃

Thanks for this amazing library anyway ❤️

Thanks for your kind words! Would you mind telling me what receiver you're using that spits out these TXT sentences?

I bought a simple gps stick (this one: https://www.amazon.com/dp/B07SMRXSC8)

I have not tested it yet, if it works with the new library, but I'll do that today, 😄

Ah interesting! I got plenty of receivers, but not this one. If you find the time I'd be interested if all sentences are parsed without a problem. Don't hesitate to open a new ticket if something is not parsed accordingly.
