What
Create Banner Patterns for patterns added by other mods

Why
If other mods like Quark use Minecraft's EnumHelper to add patterns that use items into the net.minecraft.tileentity.BannerPattern enum, it becomes inconsistent with the Banner Patterns already added by FutureMC.

How
Automatically create BannerPatternItems for each pattern in the enum.

• Could loop through BannerPattern.values and filter patterns that don't have a patternItem of ItemStack.EMPTY
• Dynamically create the meta length and copy indices over to the new pattern list

And/or, add API methods to make banner patterns or add Loom recipes

Supplement:at present, the patterns from other mods can be obtained by modifying the data value of the banner pattern, but the output of the loom is still the flower pattern.
