This commit reduces the number of nearest neighbours used in attribute
prediction to 4 from 8 in order to reduce memory usage.

This commit removes the ability to control the quantization dead-zone
parameters since they have always been identical to the step size.

Rather than hard-coding the dead-zone size parameter to be the same as
the step size, this commit:

 - Sets the dead-zone to be ±(2 * stepsize / 3) rather than ±stepsize

 - Does not narrow the interval following the dead-zone.

This commit eliminates the blending of point attribute values during
the attribute transfer process used in geometry quantisation by forcing
the blending weight to be 0|1 (m42141).

m42538 also recommends to disable the bounded search of the closest
attribute from the contributing set by setting searchRange=0.  This is
reflected by a change to the software defaults and configuration.

This commit replaces the rather verbose TMC3v0CfPParameters document
with a set of configuration files written according to the MPEG N17351
PCC common test conditions.

Unfortunately rate-point configurations are dependent on the sequence
and test category, preventing the effective use of composable configuration
files.

The configuration files are:

 - lossless-geom-no-attrs:          Condition 3.1
 - lossless-geom-lossy-texture:     Condition 3.2
 - lossless-geom-lossy-reflectance: Condition 3.3
 - lossy-geom-no-attrs:             Condition 3.4 & 3.8
 - lossy-geom-lossy-attrs:          Condition 3.6

 - per-sequence/*.cfg: source data configuration for encoding.

Simple usage documentation is added to README.md
