Random UUID (version 7) Generator

Generate Random version 7 UUID. Version 7, Unix Epoch time UUIDs are a new format of UUID, proposed in an Internet-Draft under review at the IETF. Version 7 UUIDs are binary-compatible with ULIDs (universally unique lexicographically-sortable identifiers). Both use a 48-bit timestamp in milliseconds since the Unix Epoch, filling the rest with random data. Version 7 UUIDs then add the version and variant bits required by the UUID specification, which reduces the randomness from 80 bits to 74. Otherwise, they are identical. Like version 6, version 7 UUIDs also solve two problems that have long existed with the use of version 1 UUIDs: Scattered database records and Inability to sort by an identifier in a meaningful way (i.e., insert order)
