menstrualcycleR: Phase-Aligned Cycle Time Scaling (PACTS) and Menstrual Cycle Analysis

Implements Phase-Aligned Cycle Time Scaling (PACTS) for menstrual cycle data, placing observations from cycles of differing length onto a common continuous timeline that accounts for variability in ovulation timing. Provides cycle time variables anchored on either menses onset or ovulation, summaries of how ovulation was determined in each cycle, and plotting functions for cycle-aligned outcomes. Methods are described in Nagpal et al. (2025) <doi:10.1016/j.psyneuen.2025.107584>.
