 * Converts raw diagnostic or contract events into something with a flatter,

 *
 * @returns {SorobanEvent[]}  a list of human-readable event structures, where

 *  - type: a string of one of 'system', 'contract', 'diagnostic
 *  - contractId?: optionally, a `C...` encoded strkey
 *  - topics: a list of {@link scValToNative} invocations on the topics
 *  - data: similarly, a {@link scValToNative} invocation on the raw event data
