1.1.0 - Christmas monsters

Six indoor monsters now dress up for Christmas, wherever and whenever they spawn:

Poinsettia Bracken: evergreen-green skin with its leaves turned poinsettia red, a Santa hat with a poinsettia on the brim, yellow poinsettia buds on its back, and a string of fairy lights around its waist that glow red, green, blue, gold and pink and light up its body.
Candy-Cane Coil-Head: a cream mannequin body with rust patches, a smiling painted egg head with rosy cheeks, a Santa hat with a sprig of holly, and a red-and-white candy-cane spring.
Gift-Box Jester: its music box is wrapped in red paper with a gold ribbon and a big gold bow, with a red crank. When it pops out it has a white grinning face with rosy cheeks, a red-and-green jester hat with gold bells, a red, white and green ruff collar and a pale neck.
Reindeer Thumper: reindeer antlers, a glowing red nose that lights up its face, and a striped knitted scarf with fringe.
Present Hoarder (Hoarding Bug): a Santa hat, and a wrapped present held in its mandibles.
Garland Snare Flea: red and green striped segments, gold legs, glowing string lights along its back and baubles hanging from its antennae.

Details:

Every piece rides on the monster's own skeleton, so hats, antlers, lights and scarves move with every animation.
Purely visual: the monsters behave exactly as normal. The decorations show for every player who has the mod installed, whoever is hosting.
Each monster can be switched off on its own in BepInEx\config\lethalmodzz.lethalchristmas.monsters.cfg.
No new dependencies.
