📣 Don't merge until [TDE-1740 PR is merged and released](linz/topo-imagery#1460), as the `rgbnir_zstd` compression preset will not be handled by standardising (which would only happen if someone uses that complression preset) :mega: ### Motivation To standardise RGBN imagery, we need a compression preset `rgbn_zstd` and geospatial categories of `near-infrared-aerial-photos` and `near-infrared-satellite-imagery`. ### Modifications Added these values to workflowtemplate `compression` and `category` enums. Skip the Basemaps overviews creation as ZSTD is not supported.

Motivation
As a remote sensing scientist I want RGBNIR + Alpha TIFFs available in a public bucket so that I don’t need to request data from several different councils and/or LINZ.
This requires handling RGBN which can be in the following forms:
The desired output bands are:
R/G/B/NIR/A 5-band TIFFs
Modifications
Added a new preset
rgbnir_zstdUpdated bands checks to handle RGBNIR scenarios
Updated footprint creation to handle RGBNIR
Unit tests and doctests
End-to-end test for RGBNIR
Verification
PR container, unit tests, docstring tests, end-to-end tests.
