Zs-yaml

What's Changed
* `extract_extern_as_yaml` supports compressed externals (gzip, zstd, lz4, brotli)
* `extract_extern_as_yaml` supports generating yamls without null-value fields
* New `py_eval` transformation function allows to generate node values by Python snippets

**Full Changelog**: https://github.com/ndsev/zs-yaml/compare/v0.6.1...v0.7.0

This release updates the minimum needed zserio version to 2.15.0 (latest release) and refines the interval to allow all future versions which don't break compatibility (incl. minor version updates).

**Full Changelog**: https://github.com/ndsev/zs-yaml/compare/v0.6.0...v0.6.1

This release fixes a crash which hides zserio exception messages in some cases.

This release add the `yaml_to_pyobj` conversion function (lib version only, not available via cli), which directly converts the read YAML to the corresponding zserio schema object.

We're excited to announce the first release of zs-yaml, a powerful tool that adds YAML as a text format for use with zserio, improving the user experience when creating or analyzing test data.

Features

- **YAML Format Support**: Use YAML's human-readable format instead of JSON as the primary format for editing, making data handling and transformation more intuitive and less cluttered.
- **Automatic Metadata Inclusion**: Metadata is automatically included in the YAML, eliminating the need for users to manually identify the correct type when importing JSON data, ensuring seamless (de-)serialization.
- **Custom Transformations**: Hook in custom transformations to work with familiar formats (e.g., dates or coordinate representations) instead of unfamiliar ones.
- **Bidirectional Conversion**: Convert between YAML, JSON, and binary formats with ease.
- **Template Substitution**: Use template arguments for flexible YAML content generation.
- **Built-in Transformations**: Includes useful built-in transformations like `insert_yaml_as_extern`, `insert_yaml`, and `repeat_node`.
