User home shorthand (~) support

[msdobrescu]

SftpClient does not support '~'. This is used by SSH, as linux/unix, as a shorthand for the user home.
For instance, Exists would return false for a call with ~/something, although something would exists in user's home.
Is this a SFTP protocol limitation?

It seems like it is not defined in the SFTP protocol but there is an OpenSSH extension [email protected] for servers that advertise support: https://www.sftp.net/specification. This library currently does not have any implementation/awareness of the extension
