Handle odd numbers of NodeFilters to be configured #389

Closed stevehill1981 closed 11 months ago

The previous method of merging the results from the NodeFilter instances was breaking because Ruby was treating it as a series of 2-element arrays.

If you had 0, 1 or 2 node filters configured, it would work fine; if you added a third, it would break with an ArgumentError. Adding a fourth makes it work again.

Fixes #388
