PeterO.Cbor 4.0.0

Version 4.0.0: - Fix issues with CTAP2 Canonical CBOR form - Support field serialization and deserialization in ToObject and FromObject Version 4.0.0-beta2: The features in this version include: - The CBOR library no longer stores numbers in a special form beyond the CBOR data model, which represents all "65-bit" signed integers and all "double" values. This means the CBOR library no longer stores certain numbers as EDecimal, EInteger, EFloat, etc., rather than as tagged CBOR objects. - CBORObject.CompareTo now compares objects using the default deterministic encoding comparison in the draft revision of the CBOR specification, and no longer treats numbers (objects with the former type CBORType.Number) as a special class. - CBORType.Number is deprecated; CBORObjects no longer have this type. In its place, certain numbers now have new CBORTypes Integer or FloatingPoint. - CBORObject now stores floating-point numbers internally as the bits that make them up, rather than as `double`s, to avoid data loss in conversions. - Methods were added to CBORObject to read and write floating-point numbers in terms of their bit patterns rather than as `double`s or `float`s. - Ctap2Canonical was made more strict and now works when decoding CBOR objects. - Added ReadSequence and DecodeSequence to CBORObject for reading CBOR sequences. - New CBORNumber class for storing numbers representable in CBOR. The new CBORObject.IsNumber property checks whether a CBOR object represents a number. - Bug fixes Version 4.0.0-beta1: - Support nullable types in CBORObject.ToObject. - Update Numbers library to newer version - JSONOptions.Base64Padding now has no effect. The library will now write padding as necessary when writing traditional base64 to JSON and write no padding when writing base64url to JSON. - JSONOptions.ReplaceSurrogates property added. - Restrict valid shared reference indices to integers 0 or greater. - Reject writing JSON where CBOR maps have two keys with the same string equivalent. - Improve performance of CBOR object comparisons involving big floats. Version 4.0.0-alpha2: - Support CBOR tags for IRIs and IRI references. - Add CBOREncodeOptions.DefaultCtap2Canonical field. Version 4.0.0-alpha1: - Remove all APIs obsoleted since version 3.4. This includes the BigInteger, ExtendedDecimal, and ExtendedFloat APIs, which were renamed and moved to a different library, as well as the ICBORTag and CBORTypeFilter APIs. - Changed implementation of FromObject, including imposing a nesting depth limit and supporting a CBORTypeMapper parameter. - Property name conversion rules (in PODOptions) were changed in this version with respect to FromObject. In this sense, PODOptions.RemoveIsPrefix was removed. - Certain other changes in CBOR object reading and validation were made; they are largely compatible with previous versions but may be backwards-incompatible in certain rare cases
