Update ladybug_ladybug.py - Adding text alignment and justification to "text2crv" method

It would be nice if we would add the justification parameter (argument) to the "text2crv" method of the "ResultVisualization" class (from "Ladybug_Ladybug" class).

This will not affect any of the current code calling the "text2crv" method, as by default if text justification is not supplied to ObjectTable.AddText method, bottom left justification is always used.

What do you think?

P.S.

There are more justification indexes (constants) than those inserted:

but these: 1, 3, 65536, 65537, 65538, 65540, 131073, 262145 seem to be a bit buggy (they replicate the same behavior as those enlisted in the pull request. But I guess that's the question for mcneel guys.
