"""This script is used to downlaod the skill palette data.

The Guild Wars 2 chat links for build templates use a different skill ID than
the API, so skills need to be mapped from their "skill ID" to the corresponding
"palette ID".

Some game updates may require this mapping to be updated as well, otherwise the
chat link parsing/generating functionality might be broken.

To use this script, pipe the output to src/skill_palette.json and rebuild
kondou.
