Hello,

i'm trying to connect to a server with a .ppk (putty file format) that contains a ed25519-key.

Whenever i'm trying to load the key, the exception breaks down into:

 Caused by: java.io.IOException: Unknown key type ssh-ed25519
	at net.schmizz.sshj.userauth.keyprovider.PuTTYKeyFile.readKeyPair(PuTTYKeyFile.java:158)
	at net.schmizz.sshj.userauth.keyprovider.BaseFileKeyProvider.getPublic(BaseFileKeyProvider.java:81)

As far as i read the code only RSA and DSA are supported. So i'm requesting to add ed25519 support for a PuTTy Key File aswell.

Thanks in Advance.
