Snowflake Legacy ID Generation

The `snowflake-legacy` package (current version 1.0.2) is a transitional Python library providing limited backward compatibility for users of the *original* `snowflake` PyPI package, which has since been renamed to `snowflake-uuid`. The original package was designed for generating persistent, machine-specific UUIDs (often referred to as 'snowflakes'). This `snowflake-legacy` package itself is deprecated, primarily serving as a temporary bridge after the `snowflake` PyPI name was transferred to Snowflake, Inc. Users are strongly advised to migrate to `snowflake-uuid` for continued functionality and support. It has an effectively abandoned release cadence.
