Update for Ashita v4.3

[Herschel]

Add the new expDestroyPlugin DLL export in Ashita v4.3 to allow Nameplate to load in the latest Ashita.

Fixes #12.

Can confirm this is working for Ashita v4.3, although i did have to make a small change to bytes.h since my MSVC compiler was throwing a build error on a compound literal, which I just replaced with a standard C++ union assignment
