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.
