VSoft.UUIDv7

A Delphi implementation of UUID v7 - RFC 9562

UUID Version 7 is a time-ordered UUID which encodes a Unix timestamp with millisecond precision in the most significant 48 bits. As with all UUID formats, 6 bits are used to indicate the UUID version and variant. The remaining 74 bits are randomly generated. As UUIDv7 is time-ordered, values generated are practically sequential and therefore eliminates the index locality problem.
