PyMySQL: added stub for SSCursor.readnext

[Spider84pr]

I have added stub for one function.
This is my first pull request - sorry if something wrong

Looking at the source code, shouldn't this return tuple[Any, ...] (i.e. the normal row type used in SSCursor? And SSDictCursor.SSDictCursor should return dict[str, Any], since it's deriving from DictCursorMixin?

I am very sorry.
While waiting your anwer decided to work on another annotation and added commit in wrong pull request.
Can you help me solve me this problem?
SOrry I am lacking expirience and unaable revert it

Running git revert --no-edit HEAD on the command line should do the trick. That will create a new commit that "undoes" the last commit.

THank for advice but I am afraid to do something bad or illegal - I think better wait @srittau
