neighborsOf predicate processors in filter plugin should accept multiple ids.

[senakafdo]

The current neighborsOf predicate processor introduced in #325, only provides filtering on a per-node basis. When it is required to display neighbors of not just one but several nodes, the complexity of the operation becomes O(n²). This is not particularly useful for very large graphs with many thousands of nodes.

A simple improvement to the neighborsOf predicate processor would be for it to also accept an array of ids.

The stale bot is not particularly helpful. @jacomyal what's the best way forward? Do you need a PR?

Hello @senakafdo. Sigma v1 has been deprecated and won't be maintained anymore. This said, version 2 is now out, and in v2, since sigma now relies on graphology as its graph representation, the bug you are mentioning is no longer an issue as neighbor handling should very straightforward and efficient now.

@Yomguithereal ah! nice. I should have kept my eyes wide open. I will get the refs updated. Love the new version - excellent job there.
