jTelegraf API Wrapper

[aaomidi]

So I really like the work the Telegraf team has done over here: https://telegraf.js.org/

I think their simple API design is a very strong design choice they have and I believe we can offer bindings that build on top of that.

Let's keep this issue as a tracker on what we want to do and how we want to do it.
