In simulation mode, the quote is returned in ASCII instead of bytes

[lacabra]

Describe the bug

When running in simulation mode, p2p starts and requests core for GetRegistrationParams, core returns the report in ASCII, like the following output below:

core_1       | 16:14:37 [INFO] LOG DERIVE: Ok(GetRegistrationParams { result: RegistrationParams { signing_key: "407ae45a92d1198417a42ad6ec5f9eec77276a9e", report: "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", signature: "" } })

Compare the above with the different output when running in Hardware mode, which is what p2p expects and processes (in which the report is in hex, as per what the docs specify).

To Reproduce
Steps to reproduce the behavior:

1. In the discovery-integration-tests repo, edit the following line: SGX_MODE=SW
2. Launch the network with ./launch.bash and look at the network output

Expected behavior
The format of the report should be same in both Hardware and Simulation mode, as hexadecimal, following the specification.
