The existing class offered several constructors which were mostly unnecessary. This commit eliminates all existing constructors and introduces a single new one, taking a `Slice`. The internal buffer is switched from `std::vector` to `Buffer` to save a minimum of 8 bytes (plus the buffer slack that is inherent in `std::vector`) per SHAMapItem instance.
