Dac2a bulk support

[jm-rivera]

This pull request introduces version 2.4.0 of the oda_data package, focusing on improved support for DAC2A bulk downloads, schema enhancements, and dependency updates. The most significant changes include the addition of a new DATA_TYPE_CODE field to the schema and CRS mapping, switching DAC2A bulk downloads to a dedicated function for better reliability, and ensuring that measure filters are skipped for DAC2A bulk downloads (matching CRS behavior). Comprehensive tests have been added to validate these updates.

Schema and Mapping Enhancements:

• Added a new DATA_TYPE_CODE field to the ODASchema class and mapped the datatype_code column in CRS_MAPPING to this field, supporting new data columns in CRS bulk data files. [1] [2]
• Added unit tests to verify the presence of the DATA_TYPE_CODE field in ODASchema and its mapping in CRS_MAPPING.

Bulk Download Improvements:

• DAC2A bulk downloads now use the dedicated bulk_download_dac2a() function from oda-reader for improved reliability, replacing the previous use of download_dac2a(). [1] [2]
• Added a unit test to ensure that the DAC2A bulk fetcher uses bulk_download_dac2a() and cleans data before caching.

Filter Logic Updates:

• Measure filters are now skipped for DAC2A when using bulk downloads, aligning the behavior with CRS bulk downloads.
• Added a unit test to verify that measure filters are correctly skipped for DAC2A with bulk downloads.

Dependency and Version Updates:

• Updated the oda-reader dependency from >=1.3.1 to >=1.4.1 and bumped the package version to 2.4.0. [1] [2]

Documentation:

• Updated the CHANGELOG.md to reflect all major changes in version 2.4.0.
