Implement "taxonomic view" for observations search page

[upupa-epops]

There is not a way currently, but it’s been suggested a couple times in another thread, both for the species tab:

@upupa-epops

Ability to sort Species view by taxonomical order so that related species and genera are beside each other - useful for getting an idea of where to investigate deeper when identifying.

@butterfliesoforegon

I believe that projects would also be more effective and valuable if they could display sightings in taxonomic order, instead of being ordered only by the number of sightings.

@jujurenoult

in Explore → species tab.
1- currently species are sorted by number of observations. Would be great to sort them by taxonomic order.

And the observation tab (which is think is the same request as this feature request):

@natdisc

Sort taxonomically. If I want to see the “snakes” I’ve observed it would be much more useful to see them arranged in some order (taxonomic preferable, alphabetic okay) other than date observed or date added.
