Support base64 or 62

[revington]

It would be great to have uuid's in base62/64 format for docs, urls, or for couchdb _id

I'd rather not have node-uuid be in the business of providing non-standard formats. There are just too many ambiguities around how it should be implemented (e.g. http://en.wikipedia.org/wiki/Base64#Variants_summary_table). If you want to base64-encode an RFC uuid, you can do it like thus:

> new Buffer(require('./uuid').v1(null, [])).toString('base64')
'/SezcPN7EeGWAtmjqs3xzQ=='

If anyone is interested in generating base62 UUIDs, I've created uuid-base62 for that purpose. It also exposes node-uuid for convenience.

It is 2021. I guess it may be time to reconsider this once again...? I see two major formats - Base64 and Base64URL. Please consider... I have been using helper functions for too long already...

Advantages:

• Smaller string sizes
• Lower string comparison overhead

Please see #47 (comment)

The goal of this library is to implement the RFC4122 standard, nothing more, nothing less.
