I am not a Typescript coder but I made it so you can use ranges and encrypted files

Here is my code:

https://github.com/agamemnus/node-m3u8stream/tree/master/lib
I modified index.ts (index.js) and m3u8-parser.ts (m3u8-parser.js)

I can't be bothered to try to make it work with Typescript -- just throwing it out there for anyone else.
