- implemented RSA, only signing and verifying esma_pkcs1 padded

- removed gmp-helper: chunk_to_mpz is now done with gmp functions, prime generation in prime-pool
- added prime-pool (needs priority fix)
- proof of concept RSA authentication
- mpz uses LEAK_DETECTIVE
- configuration-manager supports rsa keys
