 * supported format is "ethers", which is intended to match the way that
 * Truffle Contract currently returns values (based on the Ethers decoder).  As
 * such, it only handles ABI types, and in addition does not handle the types
 * fixed, ufixed, or function.  Note that in these cases it returns `undefined`
 * rather than throwing, as we want this function to be used in contexts where
 * it had better not throw.  It also does not handle circularities, for similar
 * reasons.
 *
 * To handle numeric types, this function takes an optional numberFormatter
 * option that tells it how to handle numbers; this function should take a
 * BigInt as input.  By default, this function will be the identity, and so
 * numbers will be represented as BigInts.
 *
 * Note that this function begins by calling abify, so out-of-range enums (that
 * aren't so out-of-range as to be padding errors) will not return `undefined`.
 * Out-of-range booleans similarly will return true rather than `undefined`.
 * However, other range errors may return `undefined`; this may technically be a
 * slight incompatibility with existing behavior, but should not be relevant
 * except in quite unusual cases.
 *
 * In order to match the behavior for tuples, tuples will be transformed into
 * arrays, but named entries will additionally be keyed by name.  Moreover,
 * indexed variables of reference type will be nativized to an undecoded hex
 * string.
