K-Sortable Globally Unique IDs (Go library)

 ksuid is an efficient, comprehensive, battle-tested Go library for
 generating and parsing a specific kind of globally unique identifier
 called a *KSUID*. This library serves as its reference implementation.
 .
 What is a KSUID?
 .
 KSUID is for K-Sortable Unique IDentifier. It is a kind of globally
 unique identifier similar to a RFC 4122 UUID, built from the ground-up
 to be "naturally" sorted by generation timestamp without any special
 type-aware logic.
 .
 In short, running a set of KSUIDs through the UNIX sort command will
 result in a list ordered by generation time.
 .
 Why use KSUIDs?
 .
 There are numerous methods for generating unique identifiers, so why
 KSUID?
 .
  1. Naturally ordered by generation time
  2. Collision-free, coordination-free, dependency-free
  3. Highly portable representations
