It adds a layer if you don't know if the type is integer, float or string.
It does not handle bytearrays here because so far there is no need. There
are two classes, Sqlite::Value and Sqlite::ValueView. Value owns the
string, ValueView holds only a view the string. So there is no allocation.
It is designed to hold Utf-8 string like Sqlite but it can be easily
converted in and from QString or QVariant but mind about that this is not
free. ValueView has no constructors on perpose because it would be
ambiguous if there would be constructors for the other primitives of
the Sqlite layer like "int64", "double" and "string view".
