0.6.0

This release contains some new useful features, and as always bumps the franz-go deps to pull in important fixes.

• adds kcl topic list as an alias for kcl metadata -t (thanks @SteadBytes!)
• adds kcl misc offset-for-leader-epoch, which is a useful command for deep debugging
• allows kcl misc list-offsets and kcl misc offset-for-leader-epoch to dump all topics if none are specified
• allows kcl group describe to describe all topics if none are specified; fixes up the -v output
• fixes kcl transact and adds a new mirror mode
