Cron expression parser and evaluator

CronSim is a library designed to parse and evaluate cron expressions with precision, aiming to replicate the behavior of Debian's cron. It is primarily used to interpret the time descriptions provided by cron syntax, determining when these events occur. By addressing quirky behaviors, such as those during Daylight Saving Time transitions, the library carefully processes cron expressions without supporting the seconds field, maintaining a focus on minimalism. It seamlessly interacts with different cron syntax features, such as the 'L' character for the last day of the month and the Nth weekday of a month. CronSim ensures that cron expressions are correctly evaluated and raises errors for invalid formats, effectively handling non-standard syntax features that do not interfere with standard operations.
