Implement protocol 3.17.0

[grouville]

Hello, First of all, thanks for the library.

It is very good, and I'm currently experimenting the creation of a language server based on it (and your puccini-language-server as a reference) 🙏

The spec just got upgraded a few days ago to 3.17.0 (05/10/2022), we should upgrade the protocol accordingly (if it's not too much effort).

I'm ready to help, still working around your code atm, but totally available 😇

Ok, I checked the changes, I think I can fire a PR by the end of week (if you don't see any complication I might have missed). Could you please assign it to me ?

[tliron]

You are an angel, thank you! Will happily assign to you.

[grouville]

I didn't forget you @tliron, still implementing the language server first before upgrading the protocol (if that's ok with you)

👋 Hi, folks. Is there anything I can do to help move this forward? I'm a new user to this library and would love to use 3.17-specific types. Thanks!

@semanticart Thank you for volunteering to submit a PR for 3.17 support. :)
