Fix errors of GEOSEARCH bybox search due to:
1. projection of the box to a trapezoid (when the meter box is converted to long / lat it's no longer a box).
2. width and height mismatch
Changes:
- New GEOSEARCH point in rectangle algorithm
- Fix GEOSEARCH bybox width and height mismatch bug
- Add GEOSEARCH bybox testing to the existing "GEOADD + GEORANGE randomized test"
- Add new fuzzy test to stress test the bybox corners and edges
- Add some tests for edge cases of the bybox algorithm
