Allow using array for constructing binary trees

[czgdp1807]

Description of the problem

Idea of using arrays for constructing binary trees originated from https://github.com/codezonediitj/pydatastructs/issues/38#issuecomment-562864441 which uses arrays for constructing binary heaps. The challenge is to make the change without breaking existing API. One approach can be using keyword arguments like, elements and the transformed API would look like,

def __new__(cls, key=None, root_data=None, comp=None,
                is_order_statistic=False, *args, **kwargs):

If the above is done then the existing tests for binary_trees.py can be shortened.

This can be done by passing the array of elements and in __new__ we can insert every element of passed array in object.tree , right?

Yes we can do that. A PR would be better for explaining the solution.
