Benchmark scramble finding across real-world competitions

[lgarron]

I have scramble JSON files from Sarah Strong:

• Canadian Championship 2023
• Rubik's WCA North American Championship 2022

I'd also love to get a few more, including Worlds 2023.

We need to extract the number (and eventually round/group structure) of scrambles for each event, so that we can tell which events are the bottleneck (especially in WASM).

If someone wants to do this before I get to it, lemme know and I'll send you the JSON files.
(I believe they don't technically contain anything private, but I'd rather not publish them directly.)
