fix: add acquisition_software_name/version fields for openmassspec-core 1.4.0

[Nathan-D-R]

Summary

• Bumps openmassspec-core from 1.3.0 to 1.4.0 in Cargo.toml (and Cargo.lock).
• Adapts to RunMetadata's two new fields (acquisition_software_name, acquisition_software_version, both Option<String>, no Default impl) at the sole production construction site, run_metadata_for in crates/opentimstdf/src/mzml.rs.
• Wired a real value rather than the minimal None, None: Reader::metadata already parses AcquisitionSoftware/AcquisitionSoftwareVersion out of analysis.tdf's GlobalMetadata table into this crate's own Metadata::acquisition_software/acquisition_software_version (String, defaulting to empty when the key is absent). run_metadata_for now maps those through, treating an empty string as None rather than surfacing Some("").
• Added two unit tests: one confirming the real values flow through (run_metadata_for_wires_up_acquisition_software), one confirming empty-string-as-absent maps to None (run_metadata_for_acquisition_software_none_when_empty).
• Note on the issue's line numbers: by the time this was picked up, the file had already grown past the #31-cited line numbers (658/672), and a re-grep for RunMetadata { turned up only the one production literal - no separate test-only RunMetadata literals exist anymore. Tests build the crate's own Metadata and go through run_metadata_for, so they pick up the new fields automatically.
• Added a CHANGELOG.md entry under ## [Unreleased].
• cargo fmt --all, cargo clippy --all-targets -- -D warnings, and cargo test --all all pass clean.

Closes #31

Test plan

• cargo fmt --all (no diff)
• cargo clippy --all-targets -- -D warnings (clean)
• cargo test --all (39/39 passing, including 2 new tests)
