fix(comid): bring ValueTriple into alignment with rev05
Browse files Browse the repository at this point in the history 
At rev00, for reference/endorsed value triples, the CoRIM spec
associated an environment with one or more measurements, allowing for
two layers of multiplicity.

Since rev01, and up to (current) rev05, the spec removed the second
layer, now associating an environment with exactly one measurement.

This commit brings our implementation into alignment with the spec,
replacing ValueTriple.Measurements collection with the single
ValueTriple.Measurement.
