Replace `--anatomical-template` and `--output-resolution` with `--output-spaces` #681

This would bring QSIPrep more in line with other preps, and would maybe make it easier to support a res-native option for cases where resolution varies across acquisitions, sessions, etc.

@mattcieslak pointed out that most recon methods require isotropic voxels, so we might need something like res-nativemax and res-nativemin to use the largest or smallest voxel dimension, respectively.

For example, if voxels are 1.7 x 1.7 x 1.718, res-nativemax would produce outputs with 1.718 x 1.718 x 1.718 voxels and res-nativemin would produce outputs with 1.7 x 1.7 x 1.7 voxels.

Satra proposed something like res-isoXmm for arbitrary isotropic resolutions in https://github.com/nipreps/fmriprep/issues/2424#issuecomment-876064758.
