feat: Adding the ability to play misc angled animations based on character direction

[ItsBradyDavis]

Feature

Similarly to how walk & speak animations can be played based on an esc_item's direction angle, using the anim_by_angle command allows for an esc_item to play an animation based on its angle.

anim_by_angle bob take_low
anim_by_angle_block bob take_low

This command will make the esc_item with global id "bob" play the directionally appropriate "take_low" animation assigned to the character's Angled Animations Array.

Angled Animations is meant to be used as an array of ESCAngledAnimationResource, which is a data object taking an animation_name String (in this case, "take_low", like picking something off the ground), and an animations Array of ESCAnimationName objects.

How To Test

1. Open up a character scene. On the top level node, under Animations -> Misc Anims, add an item to the Angled Anims array and assign a ESCAngledAnimationResource to the array.
2. Assign a string value to the animation name.
3. Assign animations equal to the number of dir angles for the character / item.
4. Run anim_by_angle {characterName} {animationName} in a .esc script

@ItsBradyDavis please take a look at the comments made in the Escoria dev channel on the Discord server. It's probably easier to discuss things there first at this point. Thanks.
