Add two Poseidon Filecoin variant multihashes

Browse Source 
Reserving the 0xb400 range for Poseidon variants, allowing FIL to
iterate on the `fcX` extension of the name where they stay with
BLS12-381 and arity=2. High security variant is for extra circuits
that are usable in case new attacks arise from the standard variant.
