Error with package with a prerelease version ("Invalid Version: 2.1.0pre")

Try knockout - in the console, you'll see Invalid Version: 2.1.0pre.

The data is:

[
    {
        "package": "knockout",
        "downloads": {
            "2.3.0": 633,
            "3.5.0": 2181,
            "3.4.1": 436,
            "3.1.0": 31,
            "2.1.0pre": 1,
            "3.0.0": 829,
            "3.2.0": 450,
            "3.4.0": 781,
            "3.5.0-beta": 10,
            "3.4.2": 5021,
            "2.2.1": 132,
            "3.3.0": 637,
            "3.5.1": 62666,
            "3.5.0-rc": 17,
            "2.1.0": 3
        }
    }
]

as you can see, 2.1.0pre (which is an invalid version) has a download. I think the logic probably needs to be updated to skip over invalid versions in groupByMajor?

I think you're correct!
Thanks for reporting!

I opened #16 which will print a message to the console if a library maintainer wants to debug or somethin'

Thanks, makes sense!
