/**
 * Creates a function that invokes the predicate properties of `source` with
 * the corresponding property values of a given object, returning `true` if
 * all predicates return truthy, else `false`.
 *
 * **Note:** The created function is equivalent to `conformsTo` with
 * `source` partially applied.
 *
 * @since 4.0.0
 * @category Util
 * @param {Object} source The object of property predicates to conform to.
 * @returns {Function} Returns the new spec function.
 * @example
 *
 * const objects = [
 *   { 'a': 2, 'b': 1 },
 *   { 'a': 1, 'b': 2 }
 * ]
 *
 * filter(objects, conforms({ 'b': function(n) { return n > 1 } }))
 * // => [{ 'a': 1, 'b': 2 }]
