Fix: field.hpp: various typos

 * `Common{Unsigned, Signed}IntegerField` is derived by the
   `Common{Unsigned,Signed}EnumerationField` class so can't be final.

 * `CommonSignedIntegerField::value` should be `int64_t`.

 * Calling single precision function instead of double.

 * `CommonStringField::operator=` methods can throw.
