This adoption allows determining the weights of each point's
predicting neighbours with a reduced influence of the, for
instance, z component.

This commit adds configuration data for new cat1 and cat3 sequences:

cat1, voxelised frames:
  boxer_viewdep_vox12
  longdress_viewdep_vox12
  loot_viewdep_vox12
  redandblack_viewdep_vox12
  soldier_viewdep_vox12
  thaidancer_viewdep_vox12

cat3, LiDaR sqeuences:
  qnxadas-junction-approach: 74 frames
  qnxadas-junction-exit:     74 frames
  qnxadas-motorway-join:     500 frames
  qnxadas-navigating-bends:  300 frames

Certain test sequences with 16-bit reflectance are actually 8-bit data that
has been scaled by 255.  This commit adds non-normative support to the
encoder and decoder to convert between the two representations through
the option "hack.reflectanceScale".

This configuration unifies the old configuration files and provides
greater test coverage.  Notable changes are:

 - configuration sets for octree vs trisoup, and pred/lift vs raht.

 - cat1 test sequences added to all test configurations

 - attribute quantization step sizes are aligned between all coding
   schemes.

 - levelOfDetailCount is unified where possible (cat3 = 10, mostly)

 - config dependent dist2 variation for a given sequence is removed

This commit updates the master configuration files to support:

 - new test conditions for cat3 tests
 - existing conditions for cat1 tests (for use by tmc13)
 - updates enc/decflags to use recommended forms
 - integrates pcerror flags (per condition / sequence)
 - adds sequence databases describing source files, and source
   parameters that may be used by other scripts.

The ctc-category-map.csv file has been removed -- a new version can be
provided if necessary.
