Please support big int about go-hashids

uint64 please

[dolmen]

HashIDs support only arrays of int64. That's how they are designed. And cross-language compatibility of HashIDs is a major feature.

But you can still encode big int or uint64 as an array of int64 on top of this library.

Hello,
I've added support for BigInt on my own, however @dolmen's comment about cross-lang compatibility stops me from PR here. If anyone is interested, then my solutions is on https://github.com/msztolcman/go-hashids - comments are welcome, I'm not fluent in GoLang :) Maybe it's not best implementation and bad vars naming in few places, but I will fix this later.

Most important part for me was to have allowed "translation" from UUID to hashid. It works well in PHP, and Go version also was required.
