Moved the bulk operation of model CPMG 2site 3d into the lib file.

This is to keep the API clean.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Lowered the number of dot operations, by pre-preparing the evolution matrix another round.

The power is in system tests always even.

The trick to removing this for loop, would be to make a general multi dot function.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Turned Mint vector into a 7,1 matrix, so dimensions fit with evolution matrix.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Lowered the number of dot iterations, by pre-prepare the dot matrix another round.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Wrote the essential dot matrix up to be initiated earlier.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Changed linked matrix/vector inner products into chained dot expressions.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Change to the target function to the model ns cpmg 2site 3d to use the reduced input to the lib function.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Fix for unit tests of model ns cpmg 2site 3d to the reduced input to the lib function.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Methods to replace math domain errors in model ns_cpmg_2site_3d, has been replaced with numpy masks.

number of points has been removed, as the masks utility replaces this.
pB is now moved to be calculated inside. This makes the lib function simpler.
k_AB and k_BA is also now calculated here.
Magnetization vector is also now filled in lib function.

Task #7807 (https://gna.org/task/index.php?7807): Speed-up of dispersion models for Clustered analysis.

Python 3 fix for the CaM frame order system test base script.
