- RecordMap needs to remain internal, but implement IReadOnlyDictionary<int, SerializationRecord> so it can be returned from a public method without exposing the type itself
- introduce new PayloadReader.Read overload that can return RecordMap via out parameter
- make SerializationRecord.ObjectId public
- make MemberReferenceRecord public, expose Reference property

- extend ArrayRecord with ElementTypeName and ElementTypeLibraryName public properties

…needed for writing to System.Windows.Forms where it's used (System.Windows.Forms compiles)

- stop using internal APIs
- fix the bugs:
	- update the record map, so mapping system class of common primtive types to PrimitiveTypeRecord<T> is visible also to those who access it via Id
	- add missing support for mapping to PrimitiveTypeRecord for IntPtr and UIntPtr
	- use GetSerializationRecord when unwrapping
- remove FormatterTypeStyle.TypesWhenNeeded test (not supported)
- remove tests for internal APIs tested in PayloadReader project:
	- RecordMapTests
	- NullRecordTests
	- ClassInfoTests
	- MemberTypeInfo

- check records by Ids to detect custom comparers for Hashtable
- ObjectRecordDeserializer needs to handle ArrayRecords and raw primitive values
- add support for jagged arrays with custom offsets (just to rejct them later)
- materialize arrays of primitive types using the provided API
- when mapping System Classes to PrimitiveTypeRecord<T> the Ids need to be preserved
- don't iterate over the same member twice
- support arrays of nullable primitives (don't represent them as ArrayRecord<ClassRecord> because they consists of MemberPrimitiveTypedRecord and NullsRecords)

…eds a discussion whether we want to support that or not)

… using any of the internal APIs

- FormatterTypeStyle.TypeAlways is a must have, remove unsupported RecordTypes from the public enum and throw NotSupportedException when they are provided
- add support for Formatters.FormatterTypeStyle.XsdString
- enable tests for FormatterTypeStyle.TypesAlways | FormatterTypeStyle.XsdStringr
