Update Poseidon Hash function names, rm HashBytes
...
Since Poseidon Hash is used because of compatibility in zkSNARK circuits, due
circuit constraints number, the hash method of [T]*big.Int is the one directly
compatible with the circuits, is the method which have the `Hash` name on it.
The method that can take arbitrary length of []*big.Int putting them in chunks
of [T]*big.Int and iterating, is called `HashSlice`. The `HashBytes` has been
removed, as is a method that will not be used in zkSNARK circuits due high
constraints number.
For zkSNARK circuits, should be used `poseidon.Hash([poseidon.T]*big.Int)`.

Optimize MiMC7 migrating from *big.Int to goff generated finite field

There is still a lot of room for optimization for MiMC7 in the way that is done internally, but will be done in the future.
