Noita MapCap 2.7.0

This release improves the stitcher in the following way:

• Add JPEG exporter, with default quality of "80".
• Add Deep Zoom Image (DZI) exporter.
• Correct some downscaling logic that gave wrong results with non power of two numbers. Not relevant in normal use.
• Correct stitched image row cache missing the last row, due to wrong rounding. Also not relevan in normal use.
• Invalidate stitched image cache based on time, this may increase RAM usage a bit, but was necessary for the DZI exporter to work.

The file extension of the output file decides which exporter is used:

• .jpg or .jpeg --> JPEG
• .png --> PNG
• .dzi --> Deep Zoom Image, which is a *.dzi file + a folder of image tiles at different zoom levels. This can be directly used with OpenSeadragon
