taxon mergers #387
Description
In parallel to taxon additions, it would be handy to have a form for taxon mergers.
e.g. https://tree.opentreeoflife.org/taxonomy/browse?id=153255 and https://tree.opentreeoflife.org/taxonomy/browse?id=6154408 are the same taxon
as are
https://tree.opentreeoflife.org/taxonomy/browse?id=464691 and https://tree.opentreeoflife.org/taxonomy/browse?id=3596802
