Struct salsa20::XSalsa20

pub struct XSalsa20(_);

XSalsa20 is a Salsa20 variant with an extended 192-bit (24-byte) nonce.

Based on the paper "Extending the Salsa20 Nonce":

https://cr.yp.to/snuffle/xsalsa-20081128.pdf

The xsalsa20 Cargo feature must be enabled in order to use this (which it is by default).
