Handle broken urls

[jm-rivera]

This pull request updates the oda_reader package to version 1.3.5, focusing on making the dataflow version handling more robust and preventing crashes when URLs do not contain a version pattern. The changes ensure that the code gracefully handles edge cases during API version fallback logic.

Improvements to dataflow version handling:

• The _get_dataflow_version() function now returns None if no version pattern is found in the URL, instead of raising an exception. This prevents crashes when the URL does not include a version.
• The dataflow version fallback logic in get_data_from_api() now only attempts to fallback if a version is actually present in the URL, further improving robustness.

Project metadata:

• Bumped the package version to 1.3.5 in pyproject.toml to reflect the new release.
• Updated the changelog to document the bugfix and clarify the improved error detection logic.
