Meta-analytic activation modeling-based parcellation
Add MAMP algorithm, as described in Yang et al. (2016).

Here is my understanding of the method:
MAMP works similarly to CBP, but skips the step of performing a MACM for each voxel. Here are the steps:
- Create an MA map for each study in the dataset.
- Concatenate MA maps across studies to create a 4D dataset.
- Extract values across studies for voxels in mask, resulting in n_voxels X n_studies array.
- Correlate "study series" between voxels to generate n_voxels X n_voxels correlation matrix.
- Convert correlation coefficients to correlation distance (1 -r) values.
- Perform clustering on correlation distance matrix.
