Has anyone else successfully updated to the latest js-algorand-sdk 3.0.0 client? We are getting errors when interacting with Pera and Defly, because of the removal of get_obj_for_encoding, which both wallets appear to depend on.

In v2 of the SDK, the Transaction, LogicSig, BaseModel and other classes had get_obj_for_encoding methods and from_obj_for_encoding static methods. These were used during the process of encoding or decoding objects from msgpack or JSON. These ad-hoc methods have been removed in v3, and in their place a new Encodable interface has been introduced, along with functions encodeMsgpack, decodeMsgpack, encodeJSON, and decodeJSON.

These changes were made to streamline, standardize, and greatly increase the capabilities of the encoding and decoding process. In v2, where get_obj_for_encoding and from_obj_for_encoding were used, these new functions may be used instead.```
