Finally! Updated for Minecraft 1.20.1!

Additions:

• Re-added the Dark Steel Riot Shield (the EnderIO shield) from version 1.x of this mod!
• Added the Dark Steel Riot Tower Shield to complement the original
• Rebalanced the above shields to have at least 2 million FE capacity

IMPORTANT: This release is *NOT* compatible from versions 1.20.2 to 1.20.6 due to breaking changes that Mojang introduced in those versions. Thanks Mojang…
