Description

Currently, the pc.cast function has a safe=True/False option, which provides a short-cut to setting the cast options.

But the actual kernel has more detailed options that can be tuned, and this is already exposed in the CastOptions class in python (allow_int_overflow, allow_time_truncate, ...). So we should ensure that we can pass such a CastOptions object to the cast kernel directly as well.
