Define ending position column

[smacker]

There is an inconsistency in java&python drivers. EndPosition.End.Col for java driver returns the position of next character and python driver returns the position of the last character. For example for code print node will have EndPosition.End.Col = 6 for java and EndPosition.End.Col = 5 for python.
Currently, it isn't defined what driver should return, so it depends on native AST.
Position should be defined and later fixed in drivers accordingly.

\cc @dennwc @juanjux what do you guys think?

It should be fixed as a part of v2 release. We are almost there.

We are experiencing this with Golang driver as well in gitbase-playground.

🤞 Waiting for v2 😄

Aware of problems with Go drivers, and it's fixed upstream as well :) Tested with bblfsh/uast-viewer#19
