Legacy_zeropoints: avoid need to re-run for halo subtraction #695

Open dstndstn opened 3 years ago

Currently, stellar halo subtraction can only be done if we pass in an existing zeropoint! Add a mode where we compute an initial zeropoint, then do halo subtraction, and then re-optimize the fluxes and recompute the final zeropoint.
