Splits an object's own property values into two groups according to a predicate function.

@param {(Object|Array|TypedArray)} obj - input object
@param {Options} [options] - function options
@param {*} [options.thisArg] - execution context
@param {string} [options.returns="values"] - if `values`, values are returned; if `keys`, keys are returned; if `*`, both keys and values are returned
@param {Function} predicate - predicate function indicating which group an element in the input object belongs to
@throws {TypeError} first argument must be an object, array, or typed array
@throws {TypeError} options argument must be an object
@throws {TypeError} last argument must be a function
@throws {TypeError} must provide valid options
@returns {(Array<Array>|Array)} group results

@example
function predicate( v ) {
    return v[ 0 ] === 'b';
}
var obj = {
    'a': 'beep',
    'b': 'boop',
    'c': 'foo',
    'd': 'bar'
};
var out = bifurcateOwn( obj, predicate );
// e.g., returns [ [ 'beep', 'boop', 'bar' ], [ 'foo' ] ]

@example

    'd': 'bar'
};
var opts = {
