Description: Implements the RAS method for adjusting a matrix to match
        target row and column totals. In RAS, a matrix A is multiplied
        on the left by a diagonal matrix R and on the right by a
        diagonal matrix S, which gives the method its name. It is also
        known as biproportional matrix balancing, iterative
        proportional fitting (IPF) or raking. The package extends it
        with lower and upper bounds on individual cells. Provides
        several algorithmic variants for handling bound violations:
        hard cell-freezing with simultaneous, sequential, or hybrid
        fixation; two dependency-free clamp-and-compensate heuristics
        (proportional redistribution and iterative renormalization);
        and a naive unconstrained-recompute baseline; together with
        thin wrapper functions exposing equivalent bounded-calibration
        methods from the 'survey' package under a common interface.
        Intended for updating or regionalizing input-output tables,
        social accounting matrices (SAMs), and other applications where
        classic RAS/IPF is used but cell-level plausibility ranges must
        be respected. References: Deming and Stephan (1940)
