Allow to export the results

[toddpi314]

Excellent work on this tool!

Now, to make it really useful cross platform, it would be smart to add a structured export option so developers can diff features between platforms.

I gamble that most devs are using this tool to figure out how to retrofit their code to be compatible for the test browser; offering an export and potential diff would create itemized lists of what features are available where.

Not a P1 since talented devs can write their own extractor.

I would love this feature, but have zero time to implement it. Any takers?

See also #57 for an advanced solution. I think allowing to export the results in a structured way is a good first step in this direction.
