`lz_archypersine`

The number whose hyperbolic sine is the operand.

long lz_archypersine( CLZNumber* leftOperand, CLZNumber* targetNumber = nullptr );

ln(x + √(x² + 1)), defined for every x, correctly rounded. The inverse hyperbolic functions come from the logarithm and the square root, with a series where those would lose digits.
