Solid Mobs 1.3 [1.18]

Solid mobs change-log

v1.3

added ability to shove mobs out of your way without punching if you get stuck, simply right click them while crouching to give a small knock-back, has a cool-down time set by config, (less effective on villagers, longer cooldown & triggers reaction from hostile mobs)
config option added to allow or disable villager collisions (A big part of villagers I believe is that they have a mind of their own, I do not want to encroach on this and have limited their shove-ability, as this means you can possibly get stuck the option to disable villager collisions has been added)
set collisions to only apply to living mobs, (prevents issues with mods like Immersive portal's portal entities)
item, item frame & painting options and collisions removed for now
fixed hostile mobs standing on their being unable to attack them

dead or dying entities no longer have collisions fixing incompatibility with fast mob farms
setting to allow invisible entity collisions (disabled by default)
item frame and painting collisions now disabled by default
fall damage transferred to a fallen upon entity now registers to the victim as an attack from the faller (e.g. hurting zombie-piglins in this way will trigger their hostility)
added Allays to the pet collision exemption list in 1.19 version
