This commit introduces two new unit tests for the osnma_msg_receiver class: 'TeslaKeyVerification' and 'OsnmaTestVectorsSimulation'. The first test verifies the Tesla key handling within the class. The second test uses real-world test vectors to simulate osnma message receiving and verifies correct parsing and processing of messages.
The OSNMA message receiver has been refactored to correct errors. It introduces new functions to process local time verification as well as DSM blocks. Flow of information between these functions is also changed, to improve readabilty and responsibility. Several TODO comments have been addressed as part of the changes. This commit also includes minor changes to the unit tests and system parameters classes.
Introduced unit tests in `gnss_crypto_test.cc` to verify the functionality set_public_key and verify_signature. The added tests check the correctness of signature verification and public key import processes. Further minor changes
