Bump ur from 0.4.1 to 0.5.0

[dependabot]

Bumps ur from 0.4.1 to 0.5.0.

Release notes

Sourced from ur's releases.

Release 0.5.0

What's Changed

• Added ur::try_encode, which returns an error for invalid custom UR types instead of panicking.
• Added ur::Decoder::resolved_fragment_count and ur::Decoder::fragment_count for reporting multipart decode progress.
• Added fountain::Decoder::resolved_fragment_count and fountain::Decoder::fragment_count for reporting fountain decode progress.
• Validate custom UR types during single-part encoding, multipart encoder construction, and decoding. Custom types must be non-empty and contain only ASCII letters, ASCII digits, or -.
• Validate multipart UR indices more strictly: indices must be non-zero and the URI path indices must match the encoded fountain part metadata.
• Added fountain::Error::InvalidChecksum and checksum verification for decoded fountain messages.
• Added fountain::Error::InvalidSequence for fountain parts with sequence number 0.
• Return bytewords::Error::InvalidWord for malformed bytewords whose hash collides with a valid byte value but whose spelling is invalid.
• Updated the crate to Rust 2024 edition.
• Updated public minicbor error types to minicbor 2.0.
