Agonite player armour animation

[Arcanorum]

Task description

A new metal armour type is to be added in an upcoming update: Agonite.
Made of a red metal, higher tier than iron, lower than dungium.
It will be a variant of the basic iron armour, but with the armour restyled to a more red colour, and with larger horns on the helmet than the warrior, and the armour covers more of the body.

This is largely a lot of the same work for the berserker task: #65
Can just do this one and lay it over the base human character animation to create the berserker.
You will probably want the base human sprites to use as a guide for what it would look like when equipped by a player, as clothing items are just sprites layered over the top of the player sprite, matching the frame of the player animation.
