HLTV has changed its websocket endpoint

[mrwhale]

Hey @andrewda
Been a while since I've used this library, but getting back into it it seems that hltv has upgraded its websocket endpoint and a few other bits and pieces during the connecting. I've played around to see how it works now and pretty sure I've got it - but will need some help integrating that back into this library

In this I was using the websocat command line client to test and connect
Endpoint - scorebot-secure.hltv.org

1. websocat "wss://scorebot-secure.hltv.org/socket.io/?EIO=3&transport=websocket"
   • On connection you will get some information back such as an sid
2. Echo to the server 61:42["readyForMatch","{\"token\":\"\",\"listId\":\"2328874\"}"]

• You should immediately start getting live matchin information

3. every so ofter you should echo back a "keep alive" of 2, the server will respond with 3. if you do not receive a response generally means the connection has closed
   Below is a print of it in action, and a look at the data structure of the json feed that it returs

mrwhale@mrwhale:~$ websocat "wss://scorebot-secure.hltv.org/socket.io/?EIO=3&transport=websocket"

You also get some useful things during the round such as
42["log","{\"log\":[{\"MatchStarted\":{\"map\":\"de_nuke\"}}]}"]
42["log","{\"log\":[{\"MatchStarted\":{\"map\":\"de_nuke\"}}]}"]

You can also submit the string
61:42["readyForScores","{\"token\":\"\",\"listIds\":[2328874]}"] to the server to get a nice summary of the match
42["score",{"mapScores":{"1":{"firstHalf":{"ctTeamDbId":5158,"ctScore":8,"tTeamDbId":9379,"tScore":7},"secondHalf":{"ctTeamDbId":9379,"ctScore":8,"tTeamDbId":5158,"tScore":6},"overtime":{"ctTeamDbId":9379,"ctScore":0,"tTeamDbId":5158,"tScore":0},"mapOrdinal":1,"scores":{"9379":15,"5158":14},"currentCtId":9379,"currentTId":5158,"map":"de_nuke","mapOver":false}},"listId":2328874,"wins":{},"liveLog":{"":true,"IrregularTeamKillsRequirement":true,"PlayersRequirement":false,"NoSuspectEventsInFirstRoundRequirement":false,"NotKnifeRoundRequirement":true,"BombInPlayRequirement":false,"KillsInFirstRoundRequirement":false,"FiveKillsWhenEnemyElliminatedRequirement less than 5 five kills in round(s) []":true,"MatchStartRequirement":true,"MapNameRequirement":true,"NoDrawRoundsRequirement":true,"FirstRoundOverRequirement":false,"RoundOneMaxEquipmentValueRequirement":true},"forcedLive":false,"forcedDead":false}]

It seems with this method you can list a number of matchId's and get an entire summary back (this is how the main page of HLTV keeps updated for all live matches

Let me know if I can help testing. If I do get some time I may submit a PR for this
