Description

Use case: In https://www.reddit.com/r/Seattle/comments/nlprut/biking_hills_map/, it would've been nice to toss &layer=steep_streets in the URL.

Any other shortcuts missing and likely useful? Maybe info panels too -- &info=b47, with the value using https://github.com/a-b-street/abstreet/blob/9fc79b1089dbe8ff8a881325f9e3a4f4c30c1e8f/game/src/common/warp.rs#L165

Research direction
Investigate URLManager::update url free param and the flag parsing in game/src/lib.rs. Implement the ability to set layers and info panels via URL parameters as described. Ensure the existing flag parsing logic is extended to handle new parameters.
