Explicitly upgrade an older SBT fit

Schema-7 fits support staged configuration, objective construction, optimization, and sampling. Upgrading is representation-only: it never runs an optimizer or sampler. Schema-3 and schema-4 fits also receive the posterior-summary and validation containers introduced by later schemas. Schema-6 fits receive the empty MSY container introduced by schema 7.

Usage

sbt_fit_upgrade(x)
