add4d97e38 fix HashBigInts() append 
Since HashBigInts() was initializing the slice and
then appending, the content of chunks was not i.e
[1,2,3] but [0,0,0,1,2,3].
Use the index on the loop and assign values w/o append.

a5eeb50d5e Upgrade to last goff version 
Upgrade to last go-iden3-crypto, which has been upgraded to the new goff
(https://github.com/ConsenSys/goff) version used for the finite fields
arithmetic, which has been significantly optimized.

Previous:
TestAddBatchBench: nCPU: 4, nLeafs: 50000, hash: Poseidon, db: badgerdb
        Add loop:       44.043418294s
        AddBatch:       3.219378868s

New:
TestAddBatchBench: nCPU: 4, nLeafs: 50000, hash: Poseidon, db: badgerdb
        Add loop:       30.915348956s
        AddBatch:       2.289317479s

Improvement (using arbo with Poseidon hash): 1.40x

ThresholdNLeafs defines the threshold number of leafs in the tree that
determines if AddBatch will work in memory or in disk. It is defined
when calling NewTree, and if set to 0 it will work always in disk.

30d8b42fd3 Add checks that len(key)<=maxKeyLen 
Add checks that the key is not bigger than maximum key length for the tree
maxLevels size, where maximum key len = ceil(maxLevels/8).

This is because if the key bits length is bigger than the maxLevels of the
tree, two different keys that their difference is at the end, will collision in
the same leaf of the tree (at the max depth).
