Add a bloom filter that keeps track of all observed entries, and
thus has no false negatives nor false positives.

Since a boolean bool filter is a saturating bloom filter with a
single bit per entry, generalize them by using SatCounter instead
of int for the filter entries.

therefore can be used everywhere.
As a side effect, Ruby was not using the filters, so
their dependency was removed.
