WIP: Update to match new specifications from dlc-specs PR 163

[maxpolizzo]

To do:

• Rename all classes and interfaces under pre163 and pre167 folders with Pre163 or Pre167 suffix (7aa86d7c3d2ba68a8d86d8ec69498707dd8bb676)
• Make sure type is returned by pre163 classes toJSON function and make sure it is not in other classes. Classes where returned type has been removed from toJSON function must have a pre163 version for backwards compatibility. (6916ce7b2c031af238a7a46197a59a3574b0ea3d)
• Fix DlcMessage.ts to handle BigSize type deserialisation (bffd2c3be4d6e788a3e9741cbcf14f4869700f01)
• DlcOffer, DlcAccept, and DlcSign, DlcCancel, DlcClose, DlcIds, DlcInfo, DlcTransactions, NodeAnnouncementMessage, 
OrderAccept, OrderIrcInfo, OrderMetadata, OrderOffer messages should use Uint16 to deserialize type, and all sub-messages should use BigSize if type is used for deserialisation (post163, type is only used for deserialisation when there are several possible sub-types for a message class)
• When the class has no sub-class, type should be inferred from the class itself (i.e. the class does not carry type), otherwise type should be added to the class
• Remove serialization of length in OracleIdentifier.ts, OrderIrcInfo.ts and OrderMetadata.ts (20c4bcab5787b2d7947fd9c7d0cc63f088f1c8b2)
• Make sure all typescript interface names do start with "I" (ca939d55a1c1da8f5fd320d8fd523bc8c78d24b4)
• Keep old reader instantiation in pre163, use new instantiation elsewhere (a7cca04b2b6dc49a59683fa41b75ce2513be145f)
• DlcOffer, DlcAccept and DlcSign and OrderOffer already have TLV streams enabled. Add TLV streams to DlcClose, OrderAccept, NodeAnnnouncementMessage , OracleAttestationV0Pre167 and OracleAnnouncementV0Pre167 (a142ab5fe728d1faac6ef76e260004f0611929b7)
• Add protocolVersion to OrderAccept (458ea8390ce9c6f809d2a72592908743b340d676)
• In messages/ContractInfo.ts, re-implement DisjointContractInfo.validate (335895bc1e7d8b53ced2e90e7c24822e13ab123a)
• In ContractDescriptor.ts an assert clause was added to the deserialize function to check that the deserialised type is as expected: generalise this everywhere (34290675df4e81c685e5686c4dce68cf5e72a86b)
• Fix imports in rocksdb package (59f4fcb762c50d6eaadeef2efbb47094be71cefe)
• Fix imports, logic and tests in core package (e63be5d80dd77098f3b98167827ba3ff96fe9517)
• Fix conflicts between packages dependencies bignumber.js and @node-dlc/bitcoin and remove unnecessary type conversions that had been used to circumvent the issue (1fbe6796cae9dd7f76503f116c6fc4c89d3ae1e1)
• Add pre-163 tests to messaging package (7cb1b78584f1ea15c37b049804b893ed5d87eb7c)
• Fix post-163 tests in messaging package (2edfc54de3d548b15d4de188aa973b93dcce86b2)
• Fix NodeAnnouncementMessage.spec.ts test (4d32771fa631e2bcb9ff42b56a4268115eca7608)
• Fix tests inrocksdb packages and generalise using offerCollateral, acceptCollateral and temporaryConntractId orders keys everywhere (19f48306a1df3dfbd4382172b685494d8ce9249a)
• Fix tests in transport package (86c783e52285282b6a31b9c0b0be44201ca52364)
• Add a toPre163 function to post-163 classes in messaging package and add corresponding tests (0fb761fd8a7b0d41f9c80183659c402e95cdbee4)
• Fix discrepancy between pre-163 test vectors and post-163 test vectors related to ScriptWitness serialisation (fd856e6196b9dc36c7e7f832e1da49e45f08de53)
• Lint messaging package (677d168ecd013c952a8a40f5e7267e79343d100e)
• Fix payout functions builders and cross-packages dependencies (3b88c99c6e6f4832fa58fa7f5df496f162f7879c)
• Rebase vs master branch
• Bump packages version numbers to 0.21.5 (55e78311d2a71e9da8651f098743adb0dad88a91)
• Rebase vs master branch again after new commit to master branch
• Fix OracleAttestationV0Pre167 calculation of deserializedBytes during deserialization (567d0e0e65bc859f9e8cd41d88184ad3ac7bc7cd)
• Check compatibility with rust-dlc
