Nebular emission with multiple metallicities in SSPs

[bd-j]

It would be great if it was possible to compute nebular emission even when SSPs of multiple metallicities are being used (e.g. with metallicity evolution in tabular SFH). This will require alterations to the addition of nebular emission in compsp. A slow implementation my be fairly straightforward (adding the nebular emission to every SSP at every likelihood call), an optimized version that only adds nebular emission to the relevant SSPs (or does it after the fact using nebular emission weighted by ssp_weights) would be more difficult.
