Allow using a Parser as a formatter about parse HOT 4 CLOSED

Similar was suggested in #100

from parse.

I think what I'm suggesting is much simpler. It could hardly be considered new functionality, just exposing existing functionality. Basically what I have in mind is:

def format(self, *args, **kwargs) -> str:
    return self._format.format(*args, **kwargs)

Does this seem reasonable?

from parse.

It seems reasonable, one thing does occur to me though that the Parser supports some "extra" types which do not make sense for a formatter, e.g.

>>> p = compile("{:w}")
>>> r = p.parse("xyz")
>>> p._format.format("abc")
ValueError: Unknown format code 'w' for object of type 'str'

So the format method may be more difficult to implement in a full-featured way, rather than just exposing ._format.format().

Looking at the Parser class, I also don't see any obvious reason why the ._format attr is internal, perhaps a (read-only) property could just be added to return the format template string, instead of a format method?

class Parser(object):
    ...

    @property
    def format(self):
        return self._format

from parse.

Wow, I didn't know about the extra types. I guess parse() is not exactly the opposite of format()...
Anyway a read-only property seems good!
