We really need to look into why these keep switching between sha1 and sha512 - it's very weird @JamieB-gu @marsavar

- Removed systematic console logs - Removed dependency on getEntriesByName - Return time elapsed since time origin for start() - Add some documentation
Hopefully gaining more insight into where improvements would be beneficial. Now logging to the console the duration of: - rendering or hydration - downloading the island’s JavaScript

What does this change?
Refactor
initPerfto simplify and shorten the code. Stop logging willy-nilly for data that we never look at.Log islands performance info: how long it took then to render or hydrate, how long to download their JavaScript.
Chore: bump lockfiles.
Why?
We need more fine-grained information about our Islands hydration. In order to know which ones are performing best and worse, and start enforcing budget, we need information broken down by Island.
