Speed up preview generation by caching a region’s Points
Properly deal with errors that may occur during generation
Add error handling config: can be set to immediately stop preview creation and tell the user or to simply skip the Point causing an issue and fill it in with safe, though not accurate, data
Add progress bar along the bottom of the preview, can be disabled in the config
Colors and gradients can now be randomized at resource load, see the wiki for how to do so via a resource pack
Add an in-built resource pack that randomizes everything
Convert most color handlers to (Registered)DataManagers
Externally this means little more than most color (gradient) definition files are in different places than before, the new locations will be on the wiki
