Format an angle as sexagesimal hours in a string.

    Arguments are:

    radians
      The angle, in radians.
    norm (default "wrap")
      The normalization mode, used for angles outside of the standard range
      of 0 to 2π. If "none", the value is formatted ignoring any potential
      problems. If "wrap", it is wrapped to lie within the standard range.
      If "raise", a :exc:`ValueError` is raised.
    precision (default 3)
      The number of decimal places in the "seconds" place to use in the
      formatted string.
    seps (default "::")
      A two- or three-item iterable, used to separate the hours, minutes, and
      seconds components. If a third element is present, it appears after the
      seconds component. Specifying "hms" yields something like "12h34m56s";
      specifying ``['', '']`` yields something like "123456".

    Returns a string.
