Sculk sensor block entity is broken (game crash)

^{Update by Mega_Spud:}
Steps to Reproduce:

1. Place a structure block
2. Place a sculk sensor within its radius
3. Save the structure block
4. Place another structure block and load the structure that contains the sculk sensor in step 3

Observed Results:
The game crashes as it tries to load the structure with the sculk sensor

Expected Results:
The game should not crash

Screenshots/Videos attached: No

Original Description:

Sculk sensors seem to use a block entity that's not implemented properly. You can observe this by exporting a structure containing a sculk sensor.

The sculk sensor data (top) is completely empty, not even including coordinates or an ID like other block entities that don't save additional data.

If a structure containing a sculk sensor is saved and then loaded again, the game crashes.
