py-asyncssh: updated to 2.2.1

Release 2.2.1:

Added optional timeout parameter to SSHClientProcess.wait() and \ 
SSHClientConnection.run() methods.
Created subclasses for SFTPError exceptions, allowing applications to more \ 
easily have distinct exception handling for different errors.
Fixed an issue in SFTP parallel I/O related to handling low-level connection \ 
failures. Thanks go to Mikhail Terekhov for reporting this issue.
Fixed an issue with SFTP file copy where a local file could sometimes be left \ 
open if an attempt to close a remote file failed.
Fixed an issue in the handling of boolean return values when \ 
SSHServer.server_requested() returns a coroutine. Thanks go to Tom van Neerijnen \ 
for contributing this fix.
Fixed an issue with passing tuples to the SFTP copy functions. Thanks go to Marc \ 
Gagné for reporting this and doing the initial analysis.
