[Bug] HD Skins (2048x2048, 4096x4096) no longer load

[KadTheHunter]

Describe the bug

HD skins no longer load correctly. This can be observed by obtaining an old HD Head, looking at it, and checking the minecraft log to see:

[11:03:25] [Render thread/WARN]:
 Discarding incorrectly sized (2048x2048) skin texture from https://education.minecraft.net/wp-content/uploads/pinkcinnamonrollplushie.png

This appears to be only an issue on 14.20, as it does not occur on 14.19

Steps to reproduce

1. Obtain and load a HD Head
2. Texture will not load
3. Check log to see warning mentioned above

It turns out Mojang actually nuked all of the old HD Head textures off the edu site, so this isn't actually an issue with your mod. My apologies.
