py-asyncssh: updated to 1.16.0

1.16.0:
Added support for Ed448 host/client keys and certificates and rewrote Ed25519 \ 
support to use the PyCA implementation, reducing the dependency on libnacl and \ 
libsodium to only be needed to support the chacha20-poly1305 cipher.
Added support for PKCS-8 format Ed25519 and Ed448 private and public keys (in \ 
addition to the OpenSSH format previously supported).
Added support for multiple delimiters in SSHReader’s readuntil() function, \ 
causing it to return data as soon as any of the specified delimiters are \ 
matched.
Added the ability to register custom key handlers in the line editor which can \ 
modify the input line, extending the built-in editing functionality.
Added SSHSubprocessProtocol and SSHSubprocessTransport classes to provide \ 
compatibility with asyncio.SubprocessProtocol and asyncio.SubprocessTransport. \ 
Code which is designed to call BaseEventLoop.subprocess_shell() or \ 
BaseEventLoop.subprocess_exec() can be easily adapted to work against a remote \ 
process by calling SSHClientConnection.create_subprocess().
Added support for sending keepalive messages when the SSH connection is idle, \ 
with an option to automatically disconnect the connection if the remote system \ 
doesn’t respond to these keepalives.
Changed AsyncSSH to ignore errors when loading unsupported key types from the \ 
default file locations.
Changed the reuse_port option to only be available on Python releases which \ 
support it (3.4.4 and later).
Fixed an issue where MSG_IGNORE packets could sometimes be sent between \ 
MSG_NEWKEYS and MSG_EXT_INFO, which caused some SSH implementations to fail to \ 
properly parse the MSG_EXT_INFO.
Fixed a couple of errors in the handling of disconnects occurring prior to \ 
authentication completing.
Renamed “session_encoding” and “session_errors” arguments in \ 
asyncssh.create_server() to “encoding” and “errors”, to match the names \ 
used for these arguments in other AsyncSSH APIs. The old names are still \ 
supported for now, but they are marked as deprecated and will be removed in a \ 
future release.
