Introduced the notion of a RandomAccessFilter that guarantees to produce a FixedBitSet.

Nested and parent/child rely on the fact that type filters produce a FixedBitSet, the RandomAccessFilter does this. By moving away from filter cache this filters will also never be evicted because of LRU reasons, which is what is desired for nested and parent/child.

Also if nested and parent/child is configured the type filters are eagerly loaded by default.

make sense, but then the `nestedTypeFilter` method needs the have the FixedBitSetService as an argument.
