Typyscript Support?

[BjornTheProgrammer]

Is your feature request related to a problem? Please describe.
When using jsmpeg-player in a typescript project, you lose the type safety in regards to the module, and also you lose the autocomplete feature that comes with typescript.

Describe the solution you'd like
Either a rewrite of the javascript files into typescript or a type .d.ts file

Describe alternatives you've considered
A solution would be to just disable types in reference to using jsmpeg-player

I made a fork where I completed most of changing the project to completely typescript. Please let me know if you would be willing to actually continue with this before I attempt to complete this fully.
