Imports custom emoji from a TAR GZIP archive specified by PATH.
Existing emoji will be skipped unless the --overwrite option
is provided, in which case they will be overwritten.
You can specify a --category under which the emojis will be
grouped together.
With the --prefix option, a prefix can be added to all
generated shortcodes. Likewise, the --suffix option controls
the suffix of all shortcodes.
With the --unlisted option, the processed emoji will not be
visible in the emoji picker (but still usable via other means)
