fix(datasets): Take mode argument into account when saving dataset (#805
Browse files Browse the repository at this point in the history 
)

* Take mode argument into account when saving dataset
* Move mode to default save args
* Revert changes to add mode to save args and add as fs arg default instead
* Separate fs save and load args again
* Add tests for coverage
* Use fs_args to pass mode for all pandas based datasets
* Make other datasets use fs_args for handling mode as well
* Refactor and make all datasets consistent
* Update release notes

## Bug fixes and other changes
* Refactored all datasets to set `fs_args` defaults in the same way as `load_args` and `save_args` and not have hardcoded values in the save methods.
