build(deps): bump securesystemslib[colors,crypto,pynacl] from 0.14.2 to 0.15.0

[dependabot-preview]

Bumps securesystemslib[colors,crypto,pynacl] from 0.14.2 to 0.15.0.

Release notes

Sourced from securesystemslib[colors,crypto,pynacl]'s releases.

v0.15.0

• Allow Blake (blake2s and blake2b) hashing algorithms (#218)
• new features
  • Add nistp384 signature verification support (#228)
  • Allow callers to provide a default keyid in format_metadata_to_key, rather than using the default keyid value of a hash of the canonical JSON of the key metadata (#225)
  • Implement files and directories abstraction as an abstract base class; StorageBackendInterface, with a concrete implementation for local filesystems; FilesystemBackend (#232). This enables users, such as tuf, to support non-local/non-traditional filesystems, so long as they provide an object implementing securesystemslib.storage.StorageBackendInterface. All functions which take a StorageBackendInterface default to creating a filesystemBackend object for local filesystem interaction when an object isn't provided. This means that behaviour remains the same as in prior (0.14.x) releases of securesystemslib, only instead of throwing exceptions rom the Python standard library a custom, generic, error is thrown: securesystemslib.exceptions.StorageError
• removed features
  • Remove support for gzipped files in load_json_file (#230)
