[Feature Request] - Use ssh-agent

[tim-tx]

Description

Based on some tests, I find that termscp is unable to handle encrypted ssh keys. Functionality added as a result of #123 and #126 fails when ssh key, e.g. ~/.ssh/id_ed25519, requires a passphrase.

Usually you would decrypt the key once and make it available to applications via ssh-agent.

If you try to use an encrypted ssh key, you will get this error: authentication failed (could not find any suitable RSA key to authenticate with). Also, in the message, an ssh key need not be an RSA key.

I also don't want to import all my ssh keys...why termscp can't get the keys from the agent like ssh or sftp CLI?

This issue is stale because it has been open for 30 days with no activity.

This would be great. I really want to use my 1Password SSH Agent for this.
