Object Editor 3.1.0

What's Changed

• Fix RLE image decoding by @LeftofZen and @duncanspumpkin in #29
  • This is a big bug fix and now all exported images except 2 in g1.dat (that require a special palette) will be exported correctly
• Ensure variably-loaded DAT object fields are 0 by @LeftofZen in #38
  • This just 'fails' an object's validation if any of the variable data fields are non-zero like they should be.
• Use ImageSharp by @LeftofZen in #91
  • A technical change in image manipulation library. No end-user effect.
• Add G1 loading function by @LeftofZen in #92
  • You can now open G1.dat! This is another features the old WinForms editor had but the new one didn't...until today.
• Fix scrollbars giving terrible UX by @ LeftofZen in #94
  • Scrollbars in the hex editor, property viewer and image table viewer are now much more user friendly and they scroll their contents and not the entire control around it.
• Sprite preview and animation by @LeftofZen in #95
  • Select multiple images (either with shift or control keys) and they'll be animated in the preview window. Also adds a zoom feature, but yes I know it has a) terrible UX and b) no nearest-neighbour scaling, but these are issues with Avalonia and will require a more in-depth fix in future. For now though, they work well enough that I'm shipping them as is. Enjoy!
