Issue Description: I wanted to notify you all that the 1.17 ore textures (deepslate) do not get hidden when the 'hide-ores' feature is enabled. I thought you all ought to know this. I will provide you with a link to my dynmap as well as an image of the issue.

• Dynmap Version: v3.2-beta-1-470 (MC: 1.17)
• Server Version: Paper version git-Paper-65 (MC: 1.17)
• Pastebin of Configuration.txt: https://pastebin.com/jA0etscR
• Server Host (if applicable): STIPE Servers Australia (inapplicable)
• Pastebin of plugins and their versions: https://pastebin.com/yBc2YB53
• Steps to Replicate: Render surface map of any world with the hide-ores feature enabled. A possible fix to be implemented for the time being is the manual implementation of each ore; dictating that the textures be replaced by deep slate.

[✅] I have looked at all other issues and this is not a duplicate
[✅] I have been able to replicate this

Looking forward to this getting updated in future versions.

This was taken from Reddit and posted here as per the suggestion of Schmensch-.

FIx added to 3.2 code - will be in next release

@kittygaming99 - fixed in 3.2+ update? Can reopen if required :)

Not only deepslate ores but also regular Copper. Same with geodes, although those might be difficult to hide since they are sort of structures
