Small helpers for generating identifiers.

Functions
Returns a random integer between 1 and 1,000,000,000.
Returns a new, time-sortable KSUID string (see BoxTurtle.Schema.Ecto.Ksuid).
Same as generate_ksuid/0.
Returns a new random (version 4) UUID string.
Functions
@spec generate_id() :: pos_integer()
Returns a random integer between 1 and 1,000,000,000.
This is not a unique identifier: values can and will collide once many are generated,
and they are not cryptographically random. Use it for test data or throwaway labels; use
generate_ksuid/0 or generate_uuid/0 for anything that must be unique.
@spec generate_ksuid() :: String.t()
Returns a new, time-sortable KSUID string (see BoxTurtle.Schema.Ecto.Ksuid).
@spec generate_uid() :: String.t()
Same as generate_ksuid/0.
@spec generate_uuid() :: String.t()
Returns a new random (version 4) UUID string.
