irelink: Fast Probabilistic Record Linkage

Performs fast, scalable probabilistic record linkage and deduplication using the Fellegi-Sunter model. Records lacking a shared unique identifier are compared across configurable dimensions using exact, fuzzy, and distance-based comparisons, with model parameters estimated via unsupervised Expectation-Maximization. Multiple SQL backends are supported through 'DBI', including execution via 'DuckDB'. This package is a translation of the Python 'splink' library by Linacre et al. (2022) <doi:10.23889/ijpds.v7i3.1794> into idiomatic R.
