Basic envelope api

[robertstypa]

API to allow reading basic envelope/manifest data without need to parse envelope using SuitEnvelopeTagged class.

Example usage:

from suit_generator import envelope
envelope = SuitEnvelope()
envelope.load('input.suit')
print(envelope.sequence_number)
print(envelope.manifest_version)
print(envelope.digest)
print(envelope.manifest_component_id)

This should simplify implementation - please refer here
