py-asyncssh: updated to 2.5.0

Release 2.5.0

Added support for limiting which identities in an SSH agent will be used when \ 
making a connection, via a new “agent_identities” config option. This change \ 
also adds compatibility with the OpenSSL config file option \ 
“IdentitiesOnly”.
Added support for including Subject Key Identifier and Authority Key Identifier \ 
extensions in generated X.509 certificates to better comply with RFC 5280.
Added support for makedirs() and rmtree() methods in the AsyncSSH SFTP client, \ 
as well as a new scandir() method which returns an async iterator to more \ 
efficiently process very large directories. Thanks go to Joseph Ernest for \ 
suggesting these improvements.
Significantly reworked AsyncSSH line editor support to improve its performance \ 
by several orders of magnitude on long input lines, and added a configurable \ 
maximum line length when the editor is in use to avoid potential \ 
denial-of-service attacks. This limit defaults to 1024 bytes, but with the \ 
improvements it can reasonably handle lines which are megabytes in size if \ 
needed.
Changed AsyncSSH to allow SSH agent identities to still be used when an explicit \ 
list of client keys is specified, for better compatibility with OpenSSH. The \ 
previous behavior can still be achieved by explicitly setting the agent_path \ 
option to None when setting client_keys.
Changed AsyncSSH to enforce a limit of 1024 characters on usernames when acting \ 
as a server to avoid a potential denial-of-service issue related to SASLprep \ 
username normalization.
Changed SCP implementation to explicitly yield to other coroutines when sending \ 
a large file to better share an event loop.
Fixed a few potential race conditions related to cleanup of objects during \ 
connection close. Thanks go to Thomas Léveil for reporting one of these places \ 
and suggesting a fix.
Re-applied a previous fix which was unintentionally lost to allow Pageant to be \ 
used by default on Windows.
