drop feature psa-crypto-conversions The feature psa-crypto-conversion requires a psa-crypto version higher than what we currently have in sid (0.9.2). We could package the latest psa-crypto (0.12 right now), but that in turn depends on mbedtls 3.0.0, which isn't in sid yet.
Disable the feature psa-crypto-conversions for now.
add crate testresult The 'testresult' crate is just a few lines of code. It does not make sense to introduce the overhead of a full blown Debian package just for this trivial functionality.
