Inline source maps option

[crisptrutski]

Write out source map as data URL rather than separate file.

@hgl just creating this issue, as we basically have the functionality, but curious to know your use case.

Would you assume / require that the inlined source map always contains sourcesContent?

[crisptrutski]

@guybedford opts = {inlineSourceMaps: true} or {sourceMaps: 'inline'}?

[guybedford]

I guess sourceMaps: 'inline' is the trend, and is easier to write.

[crisptrutski]

Well Dart doesn't support union types yet AFAIK, so it just forces annotations to any..

I guess we're helping fight the righteous battle for union types then, that's good.

Thank you for creating this issue. (Somehow I missed this issue, so sorry to chime in this late.)

I would expect inlined source map to always contain sourcesContent, since inlining already implies being self-contained. The use cause is the one I mentioned in #68: not having to make source files available to the web server.

@hgl added some changes so that the relevant option will come into effect once #68 is closed

Great, thank you for making our lives easier, really appreciate it.
