1. Added Wang's semantic similarity.     https://github.com/tanghaibao/goatools/issues/183 2. Changed code to workaround new formats in Gene Ontology Consortium's annotations    https://github.com/geneontology/go-annotation/issues/3373    https://github.com/geneontology/go-annotation/issues/3523 3. Moved reldepth calculations into its own module to support Wang's method and to give researcher ability to calc reldepths with subset of relationships   https://github.com/geneontology/go-annotation/issues/3523
