Added signature verification to the example #14

  1. The major contribution of this PR is adding a signature verification command to the sgx-iot enclave application. It loads the sealed public key and signature from files and verifies that the input file (Sensor_Data) is appropriately signed. The command is named --verify and run_demo_sgxra.sh is updated with an example
  2. Added a signature seal and save step to the --sign command of the application. This is necessary as --verify uses a signature sealed by the enclave
  3. Changed nix.build to use local files to build instead of pulling from Github repo. Otherwise local changes are not reflected in the compiled app/library. I suppose we can leave a note for developers to keep that in mind, and keep the source pulling from github for demo purposes
