API-breaking change in #1002

[Lukasa]

The PR #1002 introduced an API breaking change. Specifically, the diff changed two messages signatures in Message+JSONAdditions, from

  public init(
    jsonString: String,
    options: JSONDecodingOptions = JSONDecodingOptions()
  ) throws

  public init(
    jsonUTF8Data: Data,
    options: JSONDecodingOptions = JSONDecodingOptions()
  )

to

  public init(
    jsonString: String,
    extensions: ExtensionMap? = nil,
    options: JSONDecodingOptions = JSONDecodingOptions()
  ) throws

  public init(
    jsonUTF8Data: Data,
    extensions: ExtensionMap? = nil,
    options: JSONDecodingOptions = JSONDecodingOptions()
  )

Adding new parameters to Swift methods, even when they are defaulted, is a SemVer major. This is because functions may be referred to by their complete label set: Message.init(jsonString:options:). With this change, the previously-valid fully-qualified method name no longer exists, and so compiles fail.

We need to update the code to restore the old methods, and to instead add new methods that take the extensions field. It's fine for the method body of the old methods to simply jump to the new ones, but they must continue to exist.

I'll start a 1.10.1 release after the fix lands.

1.10.1 cut and cocoapods updated.
