.max(valueFn) fails with valueFn that returns NaN

[Ben Styles]

Actual behaviour:

Lazy(['abc', '5', 'def']).max(x => parseInt(x, 10)) // => 'abc'

Lazy(['1', '5', 'def']).max(x => parseInt(x, 10)) // => '5'

Expected behaviour:

Lazy(['abc', '5', 'def']).max(x => parseInt(x, 10)) // => '5'

Lazy(['1', '5', 'def']).max(x => parseInt(x, 10)) // => '5'

Actually been thinking about this and it's not really .max()'s responsibility to handle NaN.
