Describe the bug
When using bytes and not filling all quadrants of the block (that is why I use bytes instead of copycat blocks), the Schematicannon fails to print the block, stating that the inventory is missing "minecraft:air". If you set the cannon to "skip missing blocks", it just skips over the whole block also not printing the bytes.

To Reproduce
Steps to reproduce the behavior:

1. Place bytes in a block and leave some of it empty.
2. Create a schematic from it
3. Position the schematic, put it into the schematicannon, put enough bytes into an adjacent inventory and gunpowder into it
4. Start printing the template

Expected behavior
A block containing bytes and air is printed correctly.
