Command for most popular snaps?

I think it would be interesting to have this feature, a quick way to get the rank of the most popular snaps from the command line.

snap rank or snap top

For example, if someone is curious about the TOP 5 snaps:

snap rank -5
snap top -5

It’s a quick way to check for the best snaps and can help developers check their packages ranks.

Why the store doesn’t has a rank? It would nice to know the most popular snaps of the week/month/year. It could be a command too:
snap rank week
