Add support for ws event GUILD_MEMBERS_CHUNK about discordgo HOT 3 CLOSED

• what the hell is GUILD_MEMBERS_CHUNK
• if you have large_threshold enabled, you can send an opcode to request all the users that were withheld from you
• if you own a server with > 100 members, and you open the members settings page, you can see it when the # of members jumps up
  GUILD_MEMBERS_CHUNK is a bit more interesting than that
  4:09 PMVoltanayeah I noticed there was a query and limit field to that opcode
  4:09 PMVoltanabut I didnt see the client using them
  4:09 PMReactit does
  4:10 PMReactin the DM window
  4:10 PMReactwhen u hit the +
  4:10 PMReactthat's how it grabs the full list of users
  4:10 PMReactand queries it
  4:10 PMVoltanabut if you already downloaded all users, why query?
  4:10 PMReacti think optimization should be done
  4:10 PMReactbut its not right now lol
  4:10 PMVoltanalol
  4:10 PMDannyhow does MEMBERS_CHUNK work anyway
  4:10 PMReactu send opcode 8

so what you have to do is request for chunking (i.e. send to the websocket)
for the servers you want to get the offline members for
the servers that require chunking have a boolean property called large on ready
the chunking format is
{
    'op': 8,
    'd': {
        'guild_id': [ guild id list of servers],
        'query': '',
        'limit': 0
    }
}
you send this to the websocket
afterwards you will get GUILD_MEMBERS_CHUNK events (receive)
that are paginated at 1000 members per chunk
you can know when to stop with a new property
member_count in the guild
e.g. a member_count of 2531 means that you'll get 3 GUILD_MEMBERS_CHUNK
1000, 1000, and 531
note that these chunks also include online members

you will also require chunking for joining guilds @Skippy
in GUILD_CREATE
if large == true

So when you join a guild and it returns the guild info event, if it's large enough, offline members will not be included and we'll need to use the chunking op to fetch them.
