py-cryptography[_vectors]: updated to 2.5

2.5:
* **BACKWARDS INCOMPATIBLE:** :term:U-label strings were deprecated in
  version 2.1, but this version removes the default idna dependency as
  well. If you still need this deprecated path please install cryptography
  with the idna extra: pip install cryptography[idna].
* **BACKWARDS INCOMPATIBLE:** The minimum supported PyPy version is now 5.4.
* Numerous classes and functions have been updated to allow :term:bytes-like
  types for keying material and passwords, including symmetric algorithms, AEAD
  ciphers, KDFs, loading asymmetric keys, and one time password classes.
* Updated Windows, macOS, and manylinux1 wheels to be compiled with
  OpenSSL 1.1.1a.
* Added support for :class:~cryptography.hazmat.primitives.hashes.SHA512_224
  and :class:~cryptography.hazmat.primitives.hashes.SHA512_256 when using
  OpenSSL 1.1.1.
* Added support for :class:~cryptography.hazmat.primitives.hashes.SHA3_224,
  :class:~cryptography.hazmat.primitives.hashes.SHA3_256,
  :class:~cryptography.hazmat.primitives.hashes.SHA3_384, and
  :class:~cryptography.hazmat.primitives.hashes.SHA3_512 when using OpenSSL
  1.1.1.
* Added support for :doc:/hazmat/primitives/asymmetric/x448 when using
  OpenSSL 1.1.1.
* Added support for :class:~cryptography.hazmat.primitives.hashes.SHAKE128
  and :class:~cryptography.hazmat.primitives.hashes.SHAKE256 when using
  OpenSSL 1.1.1.
* Added initial support for parsing PKCS12 files with
  :func:~cryptography.hazmat.primitives.serialization.pkcs12.load_key_and_certificates.
* Added support for :class:~cryptography.x509.IssuingDistributionPoint.
* Added rfc4514_string() method to
  :meth:x509.Name <cryptography.x509.Name.rfc4514_string>,
  :meth:x509.RelativeDistinguishedName
  <cryptography.x509.RelativeDistinguishedName.rfc4514_string>, and
  :meth:x509.NameAttribute <cryptography.x509.NameAttribute.rfc4514_string>
  to format the name or component an :rfc:4514 Distinguished Name string.
* Added
  :meth:~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicKey.from_encoded_point,
  which immediately checks if the point is on the curve and supports compressed
  points. Deprecated the previous method
  :meth:~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicNumbers.from_encoded_point.
* Added :attr:~cryptography.x509.ocsp.OCSPResponse.signature_hash_algorithm
  to OCSPResponse.
* Updated :doc:/hazmat/primitives/asymmetric/x25519 support to allow
  additional serialization methods. Calling
  :meth:~cryptography.hazmat.primitives.asymmetric.x25519.X25519PublicKey.public_bytes
  with no arguments has been deprecated.
* Added support for encoding compressed and uncompressed points via
  :meth:~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicKey.public_bytes. Deprecated the previous method
  :meth:~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicNumbers.encode_point.
