Function allValid

allValid<T extends object | readonly unknown[]>(
    values: { [K in string | number | symbol]: Maybe<T[K]> },
    trace?: boolean,
    firstFail?: (e: JsonAccessError) => void,
): values is T
Verifies that all elements of the array or object are valid, i.e. they are not of type JsonAccessError. The function terminates on the first error found.

NOTE: this works best with a constant tuple or object defined as const, because then, if the test succeeds, no element of the tuple or object is a Maybe anymore:
```
const all = {
  a: Maybe<X> = ...
  b: Maybe<Y> = ...
} as const;
if (!allValid(all)) return;
const realA: X = all.a
const realB: Y = all.b;
```
Type Parameters
- T extends object | readonly unknown[]
Parameters
- values: { [K in string | number | symbol]: Maybe<T[K]> }
  an object or array to be inspected
- trace: boolean = false
  if true, the first error found will be reported to the console
- firstFail: (e: JsonAccessError) => void = ...
  will be called with the first error found, if any
Returns values is T
