Scru128

Maintenance

- Updated dev dependencies

Maintenance

- Improved documentation about generator's clock rollback behavior

Most notably, v3 switches the letter case of generated IDs from uppercase (e.g.,
"036Z951MHJIKZIK2GSL81GR7L") to lowercase (e.g., "036z951mhjikzik2gsl81gr7l"),
though it is technically not supposed to break existing code because SCRU128 is
a case-insensitive scheme. Other changes include the removal of deprecated APIs.
