Adds a couple new IFMR prescriptions using the SEVN models.

Also packaged with these IFMRs are corresponding fallback fraction curves which can be used to determine kicks.

Also fixes a bug in the IFMR interpolation which was found due to the PISN choices in the new IFMRs. Now, when the BHs are completely destroyed, leading to a startype of k=15, the mass will be interpolated as 0.

When the compact remnant is entirely destroyed, the IFMR grids
should denote this with the star type "15". This commit simply
includes those lines (with a final mass of zero) rather than
skipping them, which led to an incorrect linear interpolation.

I'll note that during these changes a much more major bug was found with the fallback fraction computations during the application of natal kicks, which will be fixed in another branch.
