dem-stitcher v2.5.12

Fixed

• Ruff linting and formatting
• In-memory merge of files - preserving nodata and dtypes correctly

Added

• Tests for in-memory merge
• Tests for crop profile
• Allows users to specify dst_tile_dir for location of tiles
• Allows users to specify overwrite_existing_tiles for overwriting existing tiles (should tiles need to be re-used in the same directory)

Removed

• Dependency of environment.yml on anaconda and default distributions (now only conda-forge). This is purely ascethetic as the package's highest priority channel is conda-forge.
