FormatDataIngest - Quick fix for path issue

Description

Just after approving the merge ( !20 (merged)) I realised a potential issue.

self._data_location = validate_and_convert_file_path(
    file_path=data_location,
    base=self._path_to_yaml.parent.  # <-- here
)

This would always add the YAML parent folder to the path. This would be OK 90% of the time, but what if, for example I have the YAML on my laptop, but my data is in the cloud. I would want to add the cloud path to the data and not have it appended.

I've added a check for whether the path is relative or absolute. If it's an absolute path it just uses that directly, if it's relative, it expects the YAML to be near the actual data

Expected Behavior

relative path awareness

Proposed Solution

    Used when initialising the object. If a string is given as a
    data_location, it is converted to a pathlib.Path object. If a
    pathlib.Path object is given this is returned. Other types will
    cause an error.

    Parameters
    ----------
    data_location : Union[str, Path]
        The data_location attribute from initialisation.

    Returns
    -------
    pathlib.Path
        The data_location as a pathlib.Path object.

    Raises
    ------
    ValueError
        Error if string or pathlib.Path given.

Acceptance Criteria

• Add awareness to path type
