Proposal: Have an api to retrieve the relativedelta information

dateparser is a fantastic tool to calculate a date given a literal expression like "3 years and 6 months".

However, it does not seem possible to leverage the syntactic parser to retrieve a relativedelta (https://dateutil.readthedocs.io/en/stable/relativedelta.html) structure filled with the result of the parsing.
For example if the text says:

3 years and 6 months

It would be great to obtain a structured filled with

relativedelta(year=3, month=6)

At least I could not find on the API a way to do so. The only way seems to calculate the resulting date with

dateparser.get_date_data("3 years 6 months")

then get the current date (datetime.now()) and derive the number of months. The drawback is you loose the resolution. In the example above, you will be able to calculate 42 months but won't be able to keep the original sentence meaning: 3 years and 6 months.

Start with the existing get_date_data API and the parser path it uses; the issue does not identify an implementation file or test. Compare the requested structured result with dateutil.relativedelta and define how expressions such as “3 years and 6 months” should preserve their original units, then add coverage for that behavior.
