generate standalone HTML file

We archive reports per build and that includes source-map-explorer’s output. The HTML file is generated as follows

source-map-explorer dist/bundle.min.js \
  --replace "`node -e 'console.log(process.cwd())'`/dist/" --with '' \
  --html > reports/bundle-size.html

When opening that file the screen remains empty, because the following resources could not be loaded:

• file:///-path-to-project/node_modules/source-map-explorer/node_modules/underscore/underscore.js
• file:///-path-to-project/node_modules/source-map-explorer/vendor/webtreemap.css
• file:///-path-to-project/node_modules/source-map-explorer/vendor/webtreemap.js

Those files could either be inlined - so everything is contained in the generated HTML. Or source-map-explorer could accept a destination path and copy the required resources to it. E.g.

source-map-explorer dist/bundle.min.js \
  --replace "`node -e 'console.log(process.cwd())'`/dist/" --with '' \
  --html \
  --destination reports/gustav

would create the following structure

reports/gustav
  index.html
  underscore.js
  webtreemap.css
  webtreemap.js

This was fixed by #33 and released as 1.3.1.

PR #30 shows the original --destination idea, although the option is now called --directory.
