  Log Message:
  -----------
  Support filtering EPT by OGR datasources (#2771)

* initial implementation of OGR filtering with an 'ogr' json block for readers.ept

* remove lint

* remove more lint

* Make EPT streaming occur asynchronously with a lookahead buffer of nodes.

* Handle zero-point overlaps in streaming EPT reader, for when octree bounds overlap a query but no contained points overlap.

* Respect the threads option for EPT reader streaming.

* hammer CFLAGS and CXXFLAGS due to conda injecting them

* support driver specification and openoptions

* Update EPT streaming test, correct usage of the output point layout.

* Remove constness changes unrelated to EPT streaming for PR.

* simplify filtering with OGR

* initialize m_queryGrids in initialize()

* add test of OGR filtering

* clean up ctors that are not needed
