PII Removal

Before a match is published, we remove or change these values, because they could identify a player.

Where	What we do
player_personal.name, clan_tag	Replaced with redacted.
player_name.name_new, name_old	Replaced with redacted.
player_personal.steam_id	Replaced with a letter per player (A, B, C, …) in order of first appearance. The letters restart each match.
player_chat.text	Replaced with redacted.
player_status.ping	Set to 0.
player_info.wins, rank_update.win_count	Values above 2500 are published as 2501.
header.sharecode, demo_id	Replaced with redacted.
The csds index object	sharecode, demoId and metadata.bucket are replaced with redacted, internal job ids with the match's public id, and matchDate is cut to the minute.

In the index object, each changed column's origin ends in -redacted or -capped.
