Modify the RSA key generation algorithm to check that GCD(e, p-1) = 1 and
GCD(e, q-1) = 1 when selecting prime numbers, ensuring that e and φ(n)
are coprime. This prevents ModInverse from returning nil, which would
cause private key generation to fail and result in a panic when `Precompute` is called.
