Query the username API once instead of once per player before a match

[Blatoy]

Orikaru's steamId to name API allows to query up to 250 ids at once. It would be better for Orikaru if you had only one query instead of 6.

You can add multiples IDs using this:
?action=steam-ids&params[ids][]=76561198081828267&params[ids][]=76561198034177100
