seems to fix diamond-distance wildcard with leakage models. Still need to write tests.

define proper constants (either module-level or class-level) that hold the values of what are currently magic numbers hard-coded to 1e-4.

add a second stage to leakage-aware gauge optimization

make note of idea without making half-baked changes to code

implement fully-general gate_leakage_profile and gate_seepage_profile functions. Rename subspace_projector to superop_subspace_projector.

test for matrix_tools.py:is_projector. Use np.linalg.matrix_rank in leakage.py, rather than home-brewing an equivalent function.
