Parameters
-----------------
path -- path to the files to read
filestem -- namestem of the files to read
ens_id -- name of the ensemble, required for internal bookkeeping
meson -- label of the meson to be extracted, standard value meson_0 which corresponds to the pseudoscalar pseudoscalar two-point function.
