implement client-server Proof Of Work
Mashed up a argon2-based PoW with token buckets and bloom filters.
This is intended to prevent a few abuses including:
* Using a keysafe server for general file storage, by storing a whole
lot of chunks.
* An attacker guessing names that people will use, and uploading junk
to keysafe servers under those names, to make it harder for others to use
keysafe later.
* An attacker trying to guess the names used for objects on keysafe
servers in order to download them and start password cracking.
(As a second level of defense, since the name generation hash
is expensive already.)
Completely untested, but it builds!
