We need to sort the sed.info before saving the data. The reason is that the dictionary orders the keys with a hash so it appears random. In addition the order also changes from one process to another (I suspect the hash also depends on a seed). Thanks to Yannick for pointing out this issue.

Implement a cache for the filters to compute the fluxes. Rather than passing the transmission table as an argument to compute_fnu(), which makes caching difficult and/or slow to compute the hash, we rather pass the filter name. Then the SED object fetches the filter from the database and resamples it on the optimal wavelength grid. The result is stored in cache to avoid carrying out this operation repeatedly.

Add a carriage return after we have computed the last model or analysed the last object so that the information does not get erased.

We use only a memory-based cache, so we get rid of the option. For the time being we keep the architecture in place.

Rewrite the savefluxes module to make use of the new infrastructure. Though this implementation is not terribly scalable in case of some really large arrays. It should be enough for now anyway. Famous last words.
