Reduce npm package size

[ai]

This change reduces source-map-js footprint in node_modules from 700 KB (!) to 100 KB.

Now, source-map-js is 77% of installing size of PostCSS 😓.

• Remove dist/ with webpack pre-build. Use case for pre-build is very limited and can be easily replaced by webpack on user’s side. For instance, most of my open source doesn’t have pre-build files.
• Remove long API docs from README.md in npm package by clean-publish. You will to release this package with npx clean-publish instead of npm publish

Also https://github.com/7rulnik/source-map-js/pull/6 can be merged to fix now useless package.json key,

@ai sorry for slow response

I think we should keep webpack, because currently, it is necessary for benchmarking in a browsers. Also, we can remove API documentation and replace it with link to original source-map documentation.

And I like the idea of removing comments from published code. If you think it's safe enough, so let's do it.

And as I understand, it should be major release? I'm fine with it. We can release it as 1.0.0 BTW. I thought that it will be useful to try keep in sync versions with original source-map, but seems that it doesn't make any sense.

Can we build webpack version just to use in benchmark and do not put file to npm package?

Yeap, let’s do major (1.0 or 0.7).
