Use a paginated embed to output multiple snowflakes

Previously each snowflake passed to the command would have their own embed, which may cause
the bot to send many embeds if a staff unknowingly passed it a bunch of snowflakes. This change
makes sure that we don't run into rate limits on the bot by sending all of the snowflakes in one embed.
