Human-readable definitions contain several unrecognised data names

[vaitkus]

The following data names are mentioned in data item definitions, but do not seem to be defined:

• _pd_background.air_or_thermal_diffuse_coef
• _pd_background.polynomial_coeff_list
• _pd_qpa_external_std.block_id
• _pd_phase.block_id
• _pd_calib_intensity.detector_response
• _pd_calib_intensity.block_id
• _pd_calib_intensity.incident_intensity
• _pd_calib_intensity.incident_counts

Most of these are probably due to simple typos or incorrect category names.

They're due to categories and datanames changing after the descriptions were written.
