fix: allow 'N {interval} from now' (#502)

[jakeogh]

This is a copy of PR #642 which fixes #502. I'm not sure why it was closed, or if this is the right way to re-submit it. Afaict it's a general fix that works in all cases.

Before:

$ python -c "from dateparser import parse; from datetime import datetime ; print(parse('in 2 days', settings={'RELATIVE_BASE': datetime.now()}))"
2025-05-19 00:34:29.964320

$ python -c "from dateparser import parse; from datetime import datetime ; print(parse('2 days fron now', settings={'RELATIVE_BASE': datetime.now()}))"
None

After:

$ python -c "from dateparser import parse; from datetime import datetime ; print(parse('in 2 days', settings={'RELATIVE_BASE': datetime.now()}))"
2025-05-19 00:34:29.964320

$ python -c "from dateparser import parse; from datetime import datetime ; print(parse('2 days fron now', settings={'RELATIVE_BASE': datetime.now()}))"
2025-05-19 00:34:29.964320

Can we get this merged? Would like to have support for "* from now" format

Closing and reopening to see if CI triggers.

It seems tests do not pass.

a = (<tests.test_freshness_date_parser.TestFreshnessDateDataParser testMethod=test_relative_past_dates_038_7_years_from_now>,)
kw = {}

    @wraps(func)
    def standalone_func(*a, **kw):
>       return func(*(a + p.args), **p.kwargs, **kw)
E       TypeError: test_relative_past_dates() got an unexpected keyword argument 'in_future'

.tox/min-all/lib/python3.9/site-packages/parameterized/parameterized.py:620: TypeError

The test cases were decorating the wrong function, they should pass now.

Any further news on this? This is perhaps the most common timedelta construction in natural language English.
