 coverage keeps fluctuating because of io_nex.cpp `SNexFile::~SNexFile()`, probably depends on compiler's exact version and mood???
 -> it's global `static SNexFile nex;` -> add maybe unit test instancing it as local variable to enforce exercising destructor?
 (not so simple, as unit test doesn't know the struct definition and it's private to io_nex.cpp)
