------------------
Packaging:
The rasterio._loading module, which supports DLL loading on Windows,
has been moved into __init__.py and is no longer used anywhere else
(2594).
Bug fixes:
- GeoTIFF profiles combining tiled=False and a defined blockysize are now
supported (2599).
- URLs with // in the query string are now properly parsed (2603).
- Rasterio's Python file VSI plugin now sets the position of the underlying
stream to 0 on close, resolving 2550.
