Opening explorer API seems to not be parsing query params properly

[Camsbury]

curl https://explorer.lichess.ovh/masters\?moves\=30
gives
Failed to deserialize query string: invalid type: string "30", expected usize

fixed via lichess-org/lila-openingexplorer@511c594. needs investigation for the root cause.

ah, it's nox/serde_urlencoded#33 / https://docs.rs/serde_qs/0.12.0/serde_qs/index.html#flatten-workaround
