Initial reimplementation of storage type selection: #116

Closed saxbophone closed 2 years ago

saxbophone commented 2 years ago

now picks unsigned int by default, only chooses next-smallest unsigned int if unsigned int is same size as uintmax_t for some reason (unlikely but possible?)
Nat::BASE is now of type OverflowType (I think we forgot to make that type public...)
std::numeric_limits::radix no longer gives BASE (it will overflow int, which is the type that radix is required to be), instead just returns 2

Closes #111

Hooray! This change makes the tests run noticeably faster on my dev system (and IIRC, on CI too). Who'd've thought that unsigned int, the "natural unsigned type on the given system" would be quite optimal? 😉 </sarcasm>
