Research direction

Start with algorithms::rsa::rsa_decrypt() and compare its current RNS handling with the implementation before pull request #394. Determine whether multi-prime keys should retain RNS support, then verify that keys with more than two primes work again without regressing two-prime decryption.

Written by the indexing model from the issue text.

Description

Pre-https://github.com/RustCrypto/RSA/pull/394 RNS in algorithms::rsa::rsa_decrypt() was supported for keys with any number of primes, but after that PR it's only supported for two primes. Is this functionality useful? If yes, it should be restored.
