[Rust] Release 0.45.0

Added

• bundle(schema) / async_bundle(schema) / ValidationOptions::bundle: produce a Compound Schema Document with external $ref targets embedded in a draft-appropriate container (definitions for Draft 4/6/7, $defs for Draft 2019-09/2020-12) while preserving $ref values. #791.
• CLI: jsonschema validate and jsonschema bundle subcommands. Flat invocation (jsonschema schema.json -i …) is deprecated — use jsonschema validate instead. #791.
• ValidationError::absolute_keyword_location() to get the absolute keyword location URI of the schema node that produced the error. #737.

Changed

• ValidationError::into_parts() now returns ValidationErrorParts instead of a tuple.
