How to do eg parenthesized_expression/binary_operator in python

[AckslD]

I recently added list comprehensions etc for python #24 which works nice. I also wanted to add support to turn eg

x = (1 + 1 + 1 + 1)

to

x = (
    1
    + 1
    + 1
    + 1
)

or

x = (
    1 +
    1 +
    1 +
    1
)

but this does not directly work in the current framework since the nodes we want to put on separate lines here are not the children of a single parent, they are rather in a tree of binary operations. Also the whitespace before/after the operator is tricky. Maybe nvim-treesitter/nvim-treesitter-textobjects#235 could help for the whitespace at least.
