[Feature] Investigate links with BrainTrawler

[adamltyson]

BrainTrawler provides a way for users to query public brain data registered to an atlas. It would be great to find a way to do things like:

• Query/visualise data from BrainGlobe, so users can visualise their own data alongside e.g. public transcriptomic data
• Allow users to upload their own data to BrainTrawler, after being registered to an atlas.

@adamltyson has spoken to a member of their team, and has the contact if we want to push this forwards. Currently I don't think they have a public API.

Spoke to the BrainTrawler team today. A public API could be possible, but that's likely a lot of work on both our sides. I proposed a intermediate step in which a BrainGlobe tool can generate a URL that sends the user to BrainTrawler. Something like:

from brainglobe import BrainTrawlerLink

bt = BrainTrawlerLink("allen_mouse_10um")
bt.generate_link("CP")

This hasn't been followed up, so closing for now.
