PR fixes H3IndexFilterOperator's accuracy when used with ST_Distance function. Calculations in master branch are inaccurate because: - hexagon size in is not constant per level, so using average value could lead to including too many points without verifying actual distances - distance between given point (e.g.hexagon center) and center's of n-th ring or hexagons is not uniform and varies greatly for large values of N Example: ```sql SELECT COUNT(*) FROM testTable WHERE ST_Distance(indexed_point, ST_Point(-122, 37.5, 1)) < 10000 ``` -- This is an automated message from the Apache Git Service.
