Convert svg to separated fbx including uv

svg2fbx.py

'''
# How to use

run below command at the parent directory of svg files!
`blender -b -P svg2fbx.py`

if blender exec path is not defined, please run below one. (tested only on MacOS)
`/Applications/Blender/blender.app/Contents/MacOS/blender -b -P svg2fbx.py`
