Added

Attestation key or user private keys can now be configured with the new --attestation-key and --user-private-key arguments (or ATTESTATION_PRIVATE_KEY and USER_PRIVATE_KEY through environment variables). User certificates are correctly calculated, signed from the user private keys and the attestation key.

Changed

Seed, RNG, application name and version are now fetched from the environment when Speculos starts then stored internally for further use, rather than fetched when needed during runtime. This avoids several Speculos instances from messing up with each other's environment variables.
