/**

Creates an ID generator.

The total length of the ID is the sum of the prefix, separator, and random part length.

Not cryptographically secure.

@param alphabet - The alphabet to use for the ID. Default: '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'.

@param prefix - The prefix of the ID to generate. Optional.
|
|
@param separator - The separator between the prefix and the random part of the ID. Default: '-'.

@param size - The size of the random part of the ID to generate. Default: 16.
