Tiled hydrology lattice

Browse Source 
- Stored lattice samples in compact 32x32 tiles with least-recently-used tile eviction
- Cached sampled pond rim columns in a block-resolution tile cache
- Read window coarse nodes from the fine lattice at stride 2
- Removed the window lattice and FineLatticeSource
- Sized the fine lattice for an eleven-window span and the region lattice for a seven-region span
- Updated lattice, planner and probe harness callers for the single fine lattice
