selectConfig() expects this to be fallible, throwing when the algorithms are not supported. However, the constructor also checks that algorithms are supported when constructing an HpkeConfig, which would prevent us from deserializing an HpkeConfigList with algorithms we don't recognize, so this is moot for now. I'll file an issue to improveme this separately.
