MSVC sizeof(stronk<type>) is not the same as sizeof(type)

[anders-wind]

MSVC stronk type is larger than the underlying type. Found when: static_assert(sizeof(int8_t_wrapper_type == sizeof(int8_t)); failed in CI.
This is probably due to padding, however wrapping stronk in #pragma pack(push, 1) did not help.
This might explain why construction is so much slower on MSVC
