Janky Python script to generate the requisite meta.json file to make an emoji pack that can be imported by a *key instance.

# Usage

Provide the script with a directory and it will generate a meta.json file listing every PNG/JPG/GIF/WEBP file, extrapolating the emoji name from the filename, and the category name from the directory name.

- Pass `--host` to optionally customize the hostname used as the `host` property.
- Pass `-p` to print the JSON to stdout instead of saving it.
