Add acq-operation.json schema and example file

@jwaspin FYI, ESIP codelists tend not to be up-to-date with ISO revisions. It doesn't appear they are being maintained. For instance the recent 19157: 2023 replacement standard is not reflected by ESIP documentation.

@dwalt Is https://standards.iso.org/iso/19115/resources/Codelists/gml/ a better source? Or where should we be referring to double check these are up-to-date?

@jwaspin @J-Oliveros I believe the authoritative source for all things ISO (outside of the published standards) are: https://standards.iso.org/ and https://schemas.isotc211.org/ @dwalt can verify or refute that assertion. The https://schemas.isotc211.org/ site provides links to several different views of the standards, which can be helpful, for example, viewing the "schema documentation" for MI_AcquisitionInformation is often easier than attempting to decode the acquisitionInformation.xsd on the "standards" site.

@jwaspin the ISO codelist is better than ESIP. The TC211 is probably the best source, but hard to read. In the ISO requirement documents, I identified codelist changes, though I have not done that analysis with 19157 2023.
