Automatic XLSX export

Summary

Added a function to automatically export records from an Iterable to xlsx.
Addresses #143 (closed) / https://gitlab.indiscale.com/caosdb/customers/dimr/management/-/issues/269

Focus

Does this lack any features that are necessary and might have been missed during planning? Can this be used in the intended workflow?

Test Environment

Manual tests, ideally against test data I might not have available.
Additionally, if this needs to work on Windows and there is a working VM somewhere, this should probably also be tested there, as afaik NamedTemporaryFiles are somewhat error-prone on Win.
