wip: normalize utf-8 in TextSearchIndex
wip: add mercator-tile-index option

- added QuadIndex utility functions
- lookup: calculate the bounding cells at the highest possible
  zoom-level, then just shift cell coordinates to the current level
- store features bbox in mercator projection to better match
  queries for tile rendering
- mercator index should be a database-option, not compile-time
