Name: update_amiibo_tools_lua.py

Author: Cory Solovewicz

Description:
This is a python script to automate what the updating of the amiibo_tools.lua
file which holds a lua table of all known amiibos. Previously updating the
amiibo_tools.lua was a very manual process.

This script automates the following original command:
curl https://raw.githubusercontent.com/N3evin/AmiiboAPI/master/database/amiibo.json | jq 'del(.amiibos[].release)' | jq 'del(.characters)' | pbcopy --> transform to table
And outputs the formatted file as amiibo_tools.lua
If everything goes well, this should be an updated copy of amiibo_tools.lua
which can then be placed in the /lualibs/ directory.
The temporary amiibo.json file is then deleted

Dependencies:
python3 -m pip install jq

How to run:
python update_amiibo_tools_lua.py
The script will create the file amiibo_tools.lua

After running, manually backup the original /lualibs/amiibo_tools.lua and move the
updated amiibo_tools.lua to the /lualibs/ directory.
