py-asyncssh: updated to 2.12.0

Release 2.12.0 (10 Aug 2022)
----------------------------

* Added top-level functions run_client() and run_server() which allow
  you to begin running an SSH client or server on an already-connected
  socket. This capability is also available via a new "sock" argument
  in the existing connect(), connect_reverse(), get_server_host_key(),
  and get_server_auth_methods() functions.

* Added "sock" argument to listen() and listen_reverse() functions
  which takes an already-bound listening socket instead of a host
  and port to bind a new socket to.

* Added support for forwarding break, signal, and terminal size updates
  when redirection of stdin is set up between two SSHProcess instances.

* Added support for sntrup761x25519-sha512@openssh.com post-quantum
  key exchange algorithm. For this to be available, the Open Quantum
  Safe (liboqs) dynamic library must be installed.

* Added "sig_alg" argument to set a signature algorithm when creating
  OpenSSH certificates, allowing a choice between ssh-rsa, rsa-sha2-256,
  and rsa-sha2-512 for certificates signed by RSA keys.

* Added new read_parallel() method in SFTPClientFile which allows
  parallel reads to be performed from a remote file, delivering
  incremental results as these reads complete. Previously, large
  reads would automatically be parallelized, but a result was only
  returned after all reads completed.

* Added definition of __all__ for public symbols in AsyncSSH to make
  pyright autocompletion work better. Thanks go to Nicolas Riebesel
  for providing this change.

* Updated SFTP and SCP glob and copy functions to use scandir() instead
  of listdir() to improve efficiency.

* Updated default for "ignore_encrypted" client connection option to
  ignore encrypted keys specified in an OpenSSH config file when no
  passphrase is provided, similar to what was previosuly done for
  keys with default names.

* Fixed an issue when using an SSH agent with RSA keys and an X.509
  certificate while requesting SHA-2 signatures.

* Fixed an issue with use of expanduser() in unit tests on newer versions
  of Python. Thanks go to Georg Sauthoff for providing an initial version
  of this fix.

* Fixed an issue with fallback to a Pageant agent not working properly
  on Windows when no agent_path or SSH_AUTH_SOCK was set.

* Fixed improper escaping in readuntil(), causing certain punctuation in
  separator to not match properly. Thanks go to Github user MazokuMaxy
  for reporting this issue.

* Fixed the connection close handler to properly mark channels as fully
  closed when the peer unexpected closes the connection, allowing
  exceptions to fire if an application continues to try and use
  the channel. Thanks go to Taha Jahangir for reporting this issue and
  suggesting a possible fix.

* Eliminated unit testing against OpenSSH for tests involving DSA and
  RSA keys using SHA-1 signatures, since this support is being dropped
  in some distributions of OpenSSH. These tests are still performed, but
  using only AsyncSSH code. Thanks go to Ken Dreyer and Georg Sauthoff
  for reporting this issue and helping me to reproduce it.
