Update species images in Fieldguide to be prioritised image from BIE

[kylie-m]

The recent update to allow image prioritisation in the BIE doesn't yet flow on to ALA Fieldguide. It would be excellent to add this feature.

User story: As an ALA user, I'd like to see a good-quality species image in the Fieldguide, that represents what the species looks like.

Further info:

• Make sure Fieldguide uses prioritised images from BIE
• These are available in the API: BIE / search (https://docs.test.ala.org.au/openapi/index.html?urls.primaryName=species#/Search/Search%20the%20BIE) under the 'image' field as comma delimited
• There is also a list generated in specieslist (https://lists-test.ala.org.au/speciesListItem/list/dr4778)

fieldguide uses the bie-index service /species/guids/bulklookup. This returns with information about the first preferred image. This request is not cached.

Closing this issue because this is current behaviour.
