WebAssembly port

[abdulhannanali]

Hello, Is it possible to have a Web Assembly port of Tesseract.JS, I suppose that'd be faster?

Starting from v2, we support WebAssembly, feel free to try 😄

@jeromewu Can you please clarify what you mean by supporting WebAssembly ?

Does it mean you use emscripten to compile to WebAssembly instead of asm.js in v2 ?

Thanks.

@MonsieurMan Yes, I have configured emscripten to output WebAssembly version and asm.js version. By default tesseract.js v2 will use WebAssembly version, and fallback to asm.js when the browser is not supported.

Some more information here: https://github.com/naptha/tesseract.js/blob/master/docs/local-installation.md

@jeromewu This is nice ! I'll write a small PWA using it for saving my book quotes in the next few weeks. I'll keep you updated. ☺️

Maybe you should mention WebAssembly and the fallback to asm.js in the readme upfront ? It's a good selling point !
