Description

Currently we force user to write Guid and DateTime as nullables. We do this to be more compatible with Java.
But user is more likely to operate on plain types: Guid, Guid[], DateTime, DateTime[].

We need to add these methods to API, and rename existing ones to "ReadNullableDateTime", etc..

Note that while trivial to on writer side, it will be harder to implement for readers. Currently we lookup by type ID, which will be equal for the type and it's nullable counterpart. For this reason we probably must lookup by type ID + type or simply by type.
