Description
🧐 Motivation
I replaced my SolRsaVerify library with the OpenZeppelin library. After replacing it there was no optimization equivalent in the OpenZeppelin version. Could you add this feature to the OpenZeppelin library? The difference is ~2,300 gas units on a RSA-2048 signature validation.

📝 Details
Add an additional method to the RSA.sol named pkcs1Sha256Optimized with an identical interface but optimized gas.

Research direction
Start with the RSA.sol implementation and compare its pkcs1Sha256 method with the linked SolRsaVerifyOptimized.sol reference. Trace the existing RSA validation interface and determine how the proposed pkcs1Sha256Optimized method should preserve behavior while reducing gas for RSA-2048 validation; done means the method is added with the requested interface and optimization.
