New "dispatch" selects template argument from octave-value (Bug #42424, 42425)
* find.cc (Ffind): This method now calls dispatch() rather than attempting to
handle all matrix types on its own
(findTemplated): Changed to a functor to be passed as a template template
argument to dispatch()
(findInfo): A struct that holds the other arguments to find
(n_to_find, direction, nargout)
Added unit tests for bugs 42424 and 42425
* (new file) dispatch.h (dispatch): A method for dispatching function calls to
the right templated value based on an octave_value argument.
