Universally unique, lexicographically-sortable flake ids for Racket.
A BUID is made up of a 40 bit time component and an 88 bit randomness
component. The time component represents the current number of
centiseconds since the UNIX timestamp 1586026830000.
BUIDs are represented as 22 character strings where the first 7 characters represent the 0-padded time component encoded in base 62 and the remaining 15 characters represent the 0-padded randomness component encoded in base 62.
The randomness component must have its most significant bit initially set to 0 and all ids generated within the same centisecond must increase monotonically.
In binary, BUIDs are represented as 16 bytes, encoded in network order.
