Change: build less from source

[eight04]

Fixes #5.

Current the submodule points to the latest master.

@tophf do you want to open a new issue for sourcemap? Actually, I'm not sure whether we have excluded source map calculation from less.

[tophf]

I've tried using sourcemaps in usercss-compiler.js:

      const res = await less.render(varDefs + source, {
        math: 'parens-division',
        sourceMap: {sourceMapFileInline: true},
      });

but I get "e.getSourceMapGenerator is not a function" both in current less and this one.

Other than that, the PR is probably fine because it works without sourcemaps.

What about bumping the version?

Tagged as 0.2.0

[tophf]

NPM doesn't download the new version for me even if I clear its cache manually.
Looking at package-lock.json (in Stylus) afterwards I see 0.2.0 but the url still points to the SHA of 0.1.0...
Publishing the bundle on npm would probably help.

[eight04]

We didn't publish this repo to npm. The code is fetched from Github directly:
https://github.com/openstyles/stylus/blob/f740686cb50d67b809bcfd581b37244a9fe1df0c/package.json#L16
In Stylus, we have to run:

npm install openstyles/less-bundle#v0.2.0

To switch to v0.2.0.

[tophf]

Isn't this what NPM does when I run npm install? I've already edited package.json to openstyles/less-bundle#v0.2.0

Seems like a bug in npm:
npm/cli#2844

BTW I found that we accidentally used a prod dependency:

less-bundle/package.json

Lines 44 to 46 in 42c7eb5

	"dependencies": {
	"@rollup/plugin-json": "^4.1.0"
	}

Let me fix it and tag a new version.
