Migrate IRC commands to Helix

[Felanbird]

cc: pajbot/pajbot#2117

In the context of pajbot2, all available pb2 exec commands are being deprecated via IRC, and will require migration to helix

pajbot2/pkg/modules/debug.go

Lines 64 to 83 in c767e26

	var (
	whitelistedCommands = map[string]interface{}{
	"ban": nil,
	"unban": nil,
	"timeout": nil,
	"untimeout": nil,
	"delete": nil,
	"subscribers": nil,
	"subscribersoff": nil,
	"r9kbeta": nil,
	"r9kbetaoff": nil,
	"emoteonly": nil,
	"emoteonlyoff": nil,
	"slow": nil,
	"slowoff": nil,
	"followers": nil,
	"followersoff": nil,
	"clear": nil,
	}
	)

The report system will also require moving timeout and ban commands to Helix, but I assume that will end up getting covered either way.
