Fetch Ce data for precompute jobs

Need to fetch the worm geno/pheno data.

This one is dissimilar to the other resources of phenotype data, because the annotations are made to variants/genes, not to whole organism genotypes.

Therefore, the file formats should be:

sequence_alteration | phenotype (rather than genotype)
gene | phenotype - (with the applied BF)
gene labels
sequence_alteration labels
