bloom: add func to create bloom with data and m #74

Ordinarily the From function will create a new zeroed data slice.

If we want to create a BloomFilter that is exactly identical to one we had previously, it's not possible.

Add a new function FromWithM which exposes the data slice as an argument so that we can reconstruct a BloomFilter that is identical in every way (data slice, m, k) to a remote BloomFilter.

Hi @lemire - please have a look when you have a chance.

Looks good.
