Feature: List syntax errors for a file

[davidhalter]

This should be easily possible using parso. Just rewrap the errors from there.

API would look probably like this:

Script(...).get_syntax_errors() -> List[SyntaxError]

class SyntaxError:
    line: int
    column: int

Is somebody interested in more than this API? Would be happy to have some feedback here.

On the project branch, will be released in 0.17.0.

Please let me know if this works for you. I'm happy to change certain things. I'm not sure myself if sometimes the error is shown too late (e.g. when parentheses are not closing the next token is marked as a syntax error). It is obviously debatable where the errors are shown/marked. Please let me know what you think and I might change it.
