version() returns false positives for strings that are too large

[a-p-o]

Maybe this is not how the library is intended to be used. If that is the case, then please close.

Steps to reproduce

var uuidValidate = require("uuid-validate")

// Behaves as expected
uuidValidate('b38d63b5-524f-468c-b1c8-942c8c2284325') // => false

uuidValidate.version('b38d63b5-524f-468c-b1c8-942c8c2284325') // => 4

Expected behavior

Would it make sense to have version() also return false if the UUID is invalid?

exception would be better since the input is invalid
