- Fixed several issues with the geometry utils
- Added more operations to the geometry utils
- Updated Code Recipes section to use geometry utils
- Enabled Windows CI (python 3 only)

- Added `update` command to `datacube dataset` cli
- Added `show` command to `datacube product` cli
- Added `list` and `show` commands to `datacube metadata_type` cli
- Added 'storage unit' stacker application
- Replaced `model.GeoPolygon` with `utils.geometry` library

- Fixed a data loading issue when reading HDF4_EOS datasets.

- Added support for buffering/padding of GridWorkflow tile searches
- Improved the Query class to make filtering by a source or parent dataset easier. For example, this can be used to filter Datasets by Geometric Quality Assessment (GQA). Use `source_filter` when requesting data.

- Added Polygon Drill recipe

- Fixed the affine deprecation warning
- Added `datacube metadata_type` cli tool which supports `add` and `update`
