Standard NanoID generator function

λ: g <- createSystemRandom
λ: NanoID g
NanoID {unNanoID = "x2f8yFadImeVp14ByJ8R3"}

Arguments

:: Alphabet	An `Alphabet` of your choice
-> Length	A `NanoID` length (the standard length is 21 chars)
-> GenIO	The pseudo-random number generator state
-> IO NanoID

Customable NanoID generator function

The default Alphabet, made of URL-friendly symbols.
