Full-block size comparators.

About this Mod
Adds new full-block-size comparators that function similarly to vanilla comparators:
- Comparator blocks that can be placed in horizontal and vertical orientations - 1 main input side (blue), 4 secondary input sides, and 1 output side (red).
- A weak variant of the comparator block that can receive "weak" redstone signals from the sides. Depending on the surrounding blocks, this makes the side inputs more consistent with the back input - i.e. it can accept signals from adjacent levers, but in its horizontal state, it might also accept signals from its own output if there's redstone dust in its output spot. For this reason, you might want to connect the output directly to another device e.g. a repeater, redstone lamp, piston, or another comparator, instead of redstone dust, or use redstone dust if you want to build a simple clock.
Adds new items:
- A redstone key that can read redstone signals directly from dust, and add these signals to comparator blocks. This functions as a 5th secondary input for the comparator block - greatly simplifying builds that would need a constant side signal of a specific strength. Shift-right-click to switch between read, write, and erase modes, and right-click on blocks to read, write, or erase.
Todo
More textures for the different internal & output signal levels of the comparator blocks. Unique textures for the weak comparator.
Allow individual secondary input sides to be turned off (ignore input) using the redstone key item.
Testing
This mod uses mixins to trigger some additional logic in the world wherever a comparator would be updated, which could result in some overhead. Please follow the report issues link to report about any performance issues or bugs.
