Query if a spectrum contains photon- or energy-based data.
Functions to check if source_spct and response_spct objects
contains photon-based or energy-based data.

is_photon_based returns TRUE if its argument is a
source_spct or a response_spct object that contains photon
base data and FALSE if such an object does not contain such data,
but returns NA for any other R object, including those belonging
other generic_spct-derived classes.
is_energy_based returns TRUE if its argument is a source_spct or
a response_spct object that contains energy base data and FALSE if such an
object does not contain such data, but returns NA for any other R object,
including those belonging other generic_spct-derived classes
