Mixed precision multishift test can now be performed with/without G-parity using cmdline check and can load a pregenerated configuration

Added a mixed precision multishift algorithm for which the matrix multiplies are performed in single precision but the search directions are accumulated in double precision.
...
A reliable update step is performed at a tunable frequency to correct the residual. A final mixed-prec single-shift solve is performed on each pole to perform cleanup if necessary.
A test is provided to demonstrate the algorithm.

Added copyLane function to Tensor_extract_merge.h which copies one lane of data from an input tensor object to a different lane of an output tensor object of potentially different precision
...
precisionChange lattice function now uses copyLane to remove need for temporary scalar objects, reducing register footprint and significantly improving performance
