A quick and dirty script for hq2x-ifying tMoadLoader mods

tMLhq2x.py

# This is quick and dirty script for converting the textures of an extracted tModLoader mod as described here:
# https://forums.terraria.org/index.php?threads/hq2x-and-other-image-filter-packs.51557/
# This script also needs the python hq2x implementation, which can be found here:
