reader: read sensor thickness/material from the HDF5 metadata

Browse Source 
HDF5MetadataSource ignored /entry/instrument/detector/sensor_thickness and
sensor_material and left the DetectorSetup default (320 um, Si). Read them when
present (NXmx stores thickness in metres), so reprocessing honours the recorded
sensor -- which the parallax/absorption model needs. (The acquisition path still
records the 320 um default because DetDECTRIS sets no per-model thickness; that
is a separate, acquisition-side fix.)
