Niels Lohmann d05ac29f9b Make parse_cbor_internal's top a copy so it survives pop_back() ...

top aliased container_stack.back(), and was still read (top.is_object)
right after container_stack.pop_back() destroyed the element it aliased.
Nothing currently reorders those two lines, but the comment claiming the
reference's lifetime was already fine only accounted for reallocation
from a push, not this. A trivially-copyable container_frame makes top a
copy instead, so reads of it stay valid regardless of what happens to the
stack; the one place that mutates the live entry now does so through
container_stack.back() directly rather than through top.
