Generate time based UUID, with custom format and length.

UUIDs follow alphabetical order, more suitable for database primary key.

Short UUID save more space, and little more eye candy.

Check digit can determine if an UUID is valid, maybe useful.

There are some utility scripts in `bin` directory:

- `explain.php` Disassemble UUID to parts and generated time
- `find-offset-base36.php` Find latest offset timestamp for Base36
- `find-offset-base62Short.php` Find latest offset timestamp for Base36Short
