manually specify key pair name when launching ec2?

[AlJohri]

Describe the feature
I want to specify a key pair name when launching an instance so that I can connect to the instance via SSH. I need to use SSH because I want to use SSH Agent Forwarding and SSH Tunnels which are not supported by simple-ec2 connect.

Is the feature request related to a problem?
I saw there's a PEM file in the ~/simple-ec2 folder but I can't use it to SSH like: ssh -i ~/.simple-ec2/instance_connect.pem ec2-user@xx.xxx.xx.xxx.

Describe alternatives you've considered
I could just make the EC2 on the AWS Console but what's the fun in that :)
