Describe the bug
Penetration damage is stored by position, not by block.
If you break a damaged block, then replace it, the new block will be damaged.
If you move a damaged block with a piston, the block will stop being damaged (but the piston head will be damaged).

To Reproduce
Steps to reproduce the behavior:

1. Damage a block (I used the machinegun)
2. Break the block.
3. Replace the block.
4. The block is damaged.

Expected behavior
If you break a block, the penetration damage should be removed from that position.
If you move a block, the penetration damage should move with it.
Or, the penetration damage could be stored on the block somehow.

Environment

• OS: Linux Debian 10
• Minecraft version: 1.12.2
• Forge version: 14.23.5.2847
• Immersive Intelligence version: 0.1.1
• Immersive Engineering version: 0.12-89

Now penetration should react to block changes and on client side keeps only 16 of them, for rendering performance.
