Underwater fireball penetration problems #93
Description
Atleast on 1.14.4 paper, this seems to often be called with the water as the sourceBlock and the hitFace being the direction the fireball came from a majority of the time.
For example, if the fireball is launched from the east, the hitFace is EAST and we'd need to check that sourceBlock is a fluid and the block west of it is burnable.
Sometimes it works as this code already expects. I'd recommend checking both possibilities to get maximal damage.
