the temporary dir is best option for the intermediary outputs, but
the last output(s) should be stored in a directory chosen by the user.

Asking to the user where store that files should be enough when
running the processing from a GUI, but a similar solution may be
adopted when calling the processing-framework API through
python (or even c++).

I think the output dir path should be either an input of the entire
process (e.g. a context variable when piping modules) or stored
in a plugin setting variable (as almost all the plugins do).
