[enhancement] additional custom parameters for fingerprint hash

[DanieleMancini]

First of all thanks for your work, i'm wondering if is possible to add custom parameters when generating the fingerprint hash (something like express-fingerprint do), it would be useful to get uniq ids.

Thanks.

Ooo, awesome idea. I'll look into this for sure.

Technically it should be pretty do-able.

What kind of use-case are you thinking of, more specifically?
