Add lighthouse metrics

[martinschierle]

Hey!

This is an amazing tool, thanks for creating this. One feature request though - could you add in the new lighthouse metrics? It should be somewhat easy - add 'lighthouse=1' to the API request (see here), and then add the metrics to the resultmap:

N	Lighthouse Performance Score	data.median.firstView['lighthouse.Performance']
O	Lighthouse PWA Score	data.median.firstView['lighthouse.ProgressiveWebApp']
P	Lighthouse SEO Score	data.median.firstView['lighthouse.SEO']
Q	Lighthouse Accessibility	data.median.firstView['lighthouse.Accessibility']
R	Lighthosue Best Practices Score	data.median.firstView['lighthouse.BestPractices']
S	Lighthouse Meaningful Paint	data.median.firstView['lighthouse.Performance.first-meaningful-paint']
T	Lighthouse First Interactive	data.median.firstView['lighthouse.Performance.first-interactive']
U	Lighthouse Consist. Interactive	data.median.firstView['lighthouse.Performance.consistently-interactive']

Regards,
Martin

(Sorry missed this issue before)

Probably makes sense to include an example of the how to get the lighthouse metrics in the default sheet as they are different to the others i.e. there's not a lighthouse object but a series of properties on first view.

Doing some updates to the sheet at the moment and will include an example

I've updated the template to include an example of how to get the data from the lighthouse audit.

Will update the readme to include this
