* fix/295:
  Reenabled test (mostly) covered by 242.
  Fix for columnar functions which accept `Tile` or `ProjectedRasterTile`, but claimed all return values were `Tile`. This was problematic whenever the `Tile` as reified, and the serialization of `ProjectedRasterTile` confused the `Tile` deserializer.
  Updated copyright in template.
  Update LICENSE

* develop:
  Expressions returning primitives can't return `null`, so changing how constant tiles are created to keep catalyst optimizer from pruning them.
  Added tests for rf_convert_cell_type and rf_with_no_data. Fixed a bug with counting data/no_data cells on constant tiles.
  Additional fixes for issue locationtech#242 that cropped back up.
  Bump python development version to match JVM version

  Fixed table rendering test.
  Misc tweaks to address PR feedback.
  Added ellipsis to truncated table cells in Markdown and HTML renderers.
  Bug was with changes to `rf_with_no_data` acceptance of either `Double` or `Int`, and then incorrectly changing floating point tiles into a float cell type. Fixes locationtech#304.
  Updated ShowableTile to render NoData values differently.
  Moved array function tests to RasterFunctionsSpec.
