Add IDWRasterSource #67

Closed jpolchlo closed 4 years ago

jpolchlo commented 4 years ago

Given the performance considerations encountered when using triangulation interpolation networks to generate DEMs, I'm offering an inverse distance weighted (IDW) implementation. This has been visually checked via QGIS and a modified geotrellis-pointcloud-server and appears to be functional.

Performance testing to follow.

Closes #64
