SafeMapper: Fault-Tolerant Functional Programming with Automatic Checkpointing

Provides drop-in replacements for 'purrr' and 'furrr' mapping functions with built-in fault tolerance, automatic checkpointing, and seamless recovery capabilities. When long-running computations are interrupted due to errors, system crashes, or other failures, simply re-run the same code to automatically resume from the last checkpoint. Ideal for large-scale data processing, API calls, web scraping, and other time-intensive operations where reliability is critical. For 'purrr' methodology, see Wickham and Henry (2023) <https://purrr.tidyverse.org/>.
