[Optimized] Optimized & rewritten the logic for displaying skull skin texture in GUI:
Fixed a bug on servers below version 1.12.2 where the main thread may be automatically suspended and crash due to a timeout in the connection between the fully automated core and Mojang profile server.
Added"Minecraft-Profile-Settings" setting in Merchant.yml, please refer to the comments in the configuration file for details.
Removed the "Load-Hand-Textures-From-GUI" setting as it is no longer necessary to obtain skin textures through this function.
