[rv, rad] = ERFA.af2a(s, ideg, iamin, asec)

Convert degrees, arcminutes, arcseconds to radians.

Given:

   s         char    sign:  '-' = negative, otherwise positive
   ideg      int     degrees
   iamin     int     arcminutes
   asec      double  arcseconds

Returned:

   rad       double  angle in radians

Returned (function value):

             int     status:  0 = OK
                              1 = ideg outside range 0-359
                              2 = iamin outside range 0-59
                              3 = asec outside range 0-59.999...

Notes:

1. The result is computed even if any of the range checks fail.

2. Negative ideg, iamin and/or asec produce a warning status, but the absolute value is used in the conversion.

3. If there are multiple errors, the status value reflects only the first, the smallest taking precedence.
