4287f70341 bb-matrix: Fix min and max calculations
The BB and PM ranges were originally intended to use leading 0s to
ensure all the values were the same string length, making for nice log
filenames and columnar dat files. However, not everyone will do this -
especially if it isn't documented.

Document the intent. Make the generation and parsing of dat files robust
to either method.

b8f6c225cd bb-matrix: initial scripts to record TIME(1) metrics for BB and PM combinations
The bb-matrix.sh script will run a bitbake command, building core-image-minimal
by default, for various combinations of BB_NUMBER_THREADS and PARALLEL_MAKE. It
records all relevant metrics of the TIME(1) command for each combination in a
data file.

The bb-matrix-plot.sh script can be used to visualize each of these metrics via
a 3d surface plot, either solid surface or wireframe with a value-map
projection on the XY plane.
