Add Webassembly release

[ydyote]

Hello, very nice software

I'm pretty sure webassembly compatible code is not easy to do but I think rust has some support for that

this is really just far-fetched suggestion and only because I didn't find it in the list of issues so if it is not feasible at all I get it and now it will also be documented.

keep being awesome

PS: webassembly would be insanely cool and would most likely open doors for all platforms (also android) in a perfect world

It's doable, but requires some additional work that I have not done so far.
