Adjust presentation for different use cases

[nhoizey]

I see at least two different use cases for Speedlify:

• comparative benchmark / leaderboard as on https://speedlify.netlify.app/ssg/
• monitoring as on https://speedlify.netlify.app/netlify/

Sorting the URLs based on performance results makes sense for comparative benchmarks.

But sorting URLs by alpha would IMHO make more sense for monitoring, to always keep the same order.

I see three possible solutions:

• a boolean leaderboard attribute
• a sort attribute with multiple possibles values, url and score to start with
• a type attribute with multiple possible values, leaderboard and monitoring to start with

The later allows for more personalization of reports, if the order is not the only thing to adapt.
