The comment asked whether the no-op marker 'N' may be ignored when a
string is read. It may not: at that point the next byte must be a string
length type specification, and 'N' is not one. No-ops at positions where
a value may start are already consumed by the callers through
get_ignore_noop(), so nothing is lost by not skipping them here.
Replace the TODO with a comment stating that, and add regression tests
pinning both directions: a no-op is accepted at top level (also
repeated), before and after an array element, and before an object key,
between key and value, and before the closing brace of an object of
unknown size; it is rejected where a length type specification is
expected, i.e. after the 'S' marker of a string value and as the key
length of an object of known size.
