Idea: Verifiably non-riggable shuffle algorithm for online mahjong games

1. Server should save a random bytestring PS (regenerated after each full match) for each player. PS should be visible on game UI.
2. Server should publish a global 1024-bit (128 bytes) random bytestring GS (changed every X minutes). Current and next GS should be visible on game UI.
3. When a match starts, save timestamp T1.
4. When a round starts, save timestamp T2, and generate a random bytestring R. Then, generate random seed for this round by calculating SHA512 hash of concatenation of following elements (|| denotes concatenation):

• T1
• T2
• R
• HMAC-SHA512(GS, T1 || T2 || R)
