enable error messages to display function names

[rathaustreppe]

Heyho,
I tried to use your pedantic_class decorator on a class with alot of methods and documentation.
Somewhere in this class in a docstring syntax error. But I cant find it because the error messages doesnt show any function name or text snipped or line of code.

Example of a class containing two function. One with a correct docstring syntax and one without. But of course, in a larger class it is a miracle to find the syntax error - or you have to check every method with pedantic :(

from pedantic import pedantic_class
@pedantic_class
class Foo:
    def __init__(self, a: int) -> None:
        self.a = int
    def func(self, b:str) -> str:
        """
        Function with docstring syntax error below.
        Args:
            b (str):
            simple string
        Returns:
            str: simple string
        """
        return b
    def bunk(self) -> int:
        '''
        Function with correct docstring.
        Returns:
            int: 42
        '''
        return 42

if __name__ == '__main__':
    foo = Foo(a=10)
    foo.func(b='bar')

The error log is quite large. I only copy the featureless last lines:

File "...\lib\site-packages\docstring_parser\google.py", line 106, in _build_meta
    before, desc = text.split(":", 1)
ValueError: not enough values to unpack (expected 2, got 1)
