[struct_pack][bugfix] fix broken container size cause program crash

[poor-circle]

… much memory

Why

The container size, now will check before read. But for performance, we will resize some container before check buffer, which may cause OOM/allocate too much memory.

What is changing

1. Check the size if possible before read. (such as memory stream, for user-defined stream, it should add a member function bool check(std::size_t sz);
2. If we can't check it, now container will pre-allocate at most 1M memory, and if deserialize failed, it will try to de-allocate it by call resize & shrink_to_fit(if possible).
3. fix some overflow bug when the container size is very big.
