decimal, DateTimeOffset, and Guid are the only three of the supported simple types that occupy 16 bytes. All the others are 8 bytes at max.

At the same time, there are a plenty cases when the support of that types is not needed (the simplest example - in Excel cells decimal would become double and Guid would be formatted to string). Therefore, we can save 8 bytes per instance (and increase performance a little) by providing shorted types (e.g. ShortSimpleValue and ShortSimpleValueOr<T>).

They must be convertible to and from SimpleValue and SimpleValueOr<T>.

With only two types (SimpleValue and SimpleValueOr<T>) there are already lots of copy-pasted code, especially, in tests. Structures cannot be inherited, and we are not able to cast value types to generic type-arguments, so easy ways to avoid code duplication do not fit.

Need to investigate is it possible to use dynamics (in tests, not in code) or T4 templates.

May add another value type SimpleValueType.Enum that will be stored in either _longValue or _ulongValue field, depending on the underlying type. The information about the original type will be lost but at least the value will be preserved.
