fromJson static method
Returns a new ModbusTcpConfigData instance and imports its values from
value if it's a Map, null otherwise.
Implementation
// ignore: prefer_constructors_over_static_methods

// Note 1: the values aren't checked for validity beyond being non-null.
// Note 2: this code is stripped in release mode!
