Migrate from slacker to slack-sdk

[jacobtruman]

A newly created legacy bot token fails to authenticate using the older auth method used by the slacker module. The rtm.start method has also been deprecated, so migrated to rtm.connect. The slack-sdk module also provides blocks support.

Resolves #227.
Resolves #210.
Resolves #209.

@jacobtruman this is promising. I tested it with my own bot and encountered an issue though:

the bot enters an infinite loop due to rtm websocket disconnect:

2021-12-23 19:41:11,009 - slackbot.slackclient - WARNING - reconnected to slack rtm websocket
2021-12-23 19:41:16,020 - slackbot.slackclient - WARNING - lost websocket connection, try to reconnect now

Should we look into using the RTMClient instead?

@amuraru good catch - is this something easily duplicated, so that I can properly test it?

@amuraru I was able to duplicate this issue and added a ping to the parse user and channel data methods to prevent websocket disconnect. I am looking into implementing using RTMClient, but it looks like it might be a pretty hefty rewrite - I still think it is a good idea and am still experimenting with it.
