Performs gradient nonlinearity correction when turned on (--correct_grad "on") given the gradient coil tensor.
Main features added:
APPS/gradtensor - All the script for gradient nonlinearity correction. First, corrected voxel-wise bvec and bvals are computed. Next, an approximation that reconstructs the corrected diffusion weighted image
src/CODE/vis.py - Visualization for gradient nonlinearity correction
Added all the required functions in src/CODE/dtiQA_v7/ and package dependencies in venv/pip_install_gradtensor.txt
