Improvements and fixes include:
* Support for `ec2-ssh --send-key` - dynamically add SSH keys to the instance at the connection time
* Renamed `ssm-session` to `ec2-session` and `ssm-ssh` to `ec2-ssh`
* Lots of minor fixes and internal changes, e.g. Python type hints
**Install** with `pip install aws-ssm-tools` as usual.
