Sulfur Cubes summon Falling Block when eaten by Frog

This datapack is not well-optimised, and it primarily serves as a proof of concept.

Features:

• Frogs target small sulfur cubes
• Frogs eat sulfur cubes
• When a large sulfur cube is eaten, a frog will spit out a small sulfur cube
• When a sulfur cube with a block inside is eaten, there will be summoned a falling block. It retains the velocity of the sulfur cube.

You can also easily change the delay parameters (example with default values in ticks):

If you want to prevent frogs from spitting out a small sulfur cubes, set spit_delay higher than eat_cooldown.
