Bump ecdsa from 0.13.3 to 0.14.1 in /contrib/deterministic-build

[dependabot]

Bumps ecdsa from 0.13.3 to 0.14.1.

Release notes

Sourced from ecdsa's releases.

ecdsa 0.14.1

Remove the obsolete six.py file from wheel distribution file on pypi

ecdsa 0.14

tl;dr:

• support for Brainpool curves
• better test coverage, fixed bugs found by it
• support for compressed point representation

Bug fixes:

• Strict checking of DER requirements when parsing SEQUENCE, INTEGER,
  OBJECT IDENTIFIER and BITSTRING objects.
• DER parsers now consistently raise UnexpectedDER exception on malformed DER
  encoded byte strings.
• Make sure that both malformed and invalid signatures raise BadSignatureError.
• Ensure that all SigningKey and VerifyingKey methods that should accept
  bytes-like objects actually do accept them (also avoid copying input strings).
• Make SigningKey.sign_digest_deterministic use default object hashfunc when
  none was provided.
• encode_integer now works for large integers.
• Make encode_oid and remove_object correctly handle OBJECT IDENTIFIERs
  with large second subidentifier and padding in encoded subidentifiers.

New features:

• Deterministic signature methods now accept extra_entropy parameter to further
  randomise the selection of k (the nonce) for signature, as specified in
  RFC6979.
• Recovery of public key from signature is now supported.
• Support for SEC1/X9.62 formatted keys, all three encodings are supported:
  "uncompressed", "compressed" and "hybrid". Both string, and PEM/DER will
  automatically accept them, if the size of the key matches the curve.
• Benchmarking application now provides performance numbers that are easier to
  compare against OpenSSL.
• Support for all Brainpool curves (non-twisted).

New API:

• CurveFp: __str__ is now supported.
• SigningKey.sign_deterministic, SigningKey.sign_digest_deterministic and
• generate_k: extra_entropy parameter was added
• Signature.recover_public_keys was added
• VerifyingKey.from_public_key_recovery and
• VerifyingKey.from_public_key_recovery_with_digest were added
• VerifyingKey.to_string: encoding parameter was added
• VerifyingKey.to_der and SigningKey.to_der: point_encoding parameter was
  added.
• encode_bitstring: unused parameter was added

... (truncated)
