Changes

CombineRGBA

• Add combining RGBA a new mode for combining RGBA-split image pairs from Dolphin.
• stores an alternative version if it could not be determined exactly which is the right version.

Finalize

• Removes alpha data from opaque textures.
• Removes color data from grayscale textures.
• Limits the alpha range for CMPR terxtures.
• Change the size if necessary to the next possible correct size.
• Quantizes textures in C4 format and limits the number of different colors to 256.
• Moves duplicated textures into a separate directory.
• Result now shows the number of textures, optimizations, duplicates, old & new texture size and space saved in %.
• Prevents crashes on corrupted png files.
• Finalize can now also optimize textures without dolphin hash.

Full Changelog: v1.7.2...v1.7.13

Now texture pairs can be automatically combined to one RGBA texture.

The new CombineRGBA mode automatically searches for texture pairs and combines them to a texture with RGBA texture hash, so already dumped textures from dolphin can be easily converted to RGBA textures for easier editing.

The Finalize option has a lot of further optimizations.

A lot of unnecessary data can now be removed from png packs, saving on average 20-40%.
Thanks to @BigheadSMZ for many good suggestions for improvement.
