Compile to JS

[enthus1ast]

It would be nice to generate QRcodes on the JS backend in the browser. Currently it fails with:

import QRgen
let urlQR = newQR("https://my-url.domain")
echo urlQR.printSvg

nim js -r "qrgent.nim"

Seems like it's an issue related to encodings, which will most likely be removed in #18, so let's see if it works after that.

[enthus1ast]

with disabled encoding ( #18 ) and some small changes it works nicely on the js backend: https://github.com/enthus1ast/QRgen/tree/js

Nice! Will commit the fix to 18 when I get home in some hours, or if possible you could make a PR to develop :)

The last commit fixed the issue.

(The only issue I see is that there is no stdout in JS)
