Crate textnonce

A nonce is a cryptographic concept of an arbitrary number that is never used more than once.

TextNonce is a nonce because the first 16 characters represents the current time, which will never have been generated before, nor will it be generated again, across the period of time in which a Timespec (or std::time::Duration, counting from the UNIX epoch) is valid.

TextNonce additionally includes bytes of randomness, making it difficult to predict. This makes it suitable to be used for a session ID.

It is also text-based, using only characters in the base64 character set.

Various length TextNoncees may be generated. The minimum length is 16 characters, and lengths must be evenly divisible by 4.
