With lots of typical arguments.
Arguments prefixed by a single hyphen:
`python -region GS -year 2007 -fix d 01`
Returns a dictionnary of arguments.
args: list of str
List of typical arguments. Can include: 'data_type' (default 'OC'),
'region' (default 'GS'), 'year' (default '2007'),
'date' (default '200701'), 'fix'.
Those (and other arguments) will be added to the resulting dictionnary.
`dargs[arg] = vars(parser.parse_args())[arg][0]`.
'date' will be transformed into argument 'date': a datetime instance,
and 'date_str', a tuple of strings (year, month, day).
Specifying day is optional.
There can be any number of 'fix' arguments. Each is a couple of
key (int/str) and value (str). Each is appended to dictionnary of fixes.
See xarray_regex.FileFinder.fix_matchers().

Function that take an argparse.ArgumentParser and add arguments to it.
