Incorrect signature for MicroInterpreter initialization

[johnosbb]

In classification.ino

The call to initialize the MicorInterpreter is:
// Initialize the TFLu interpreter
tflu_interpreter = new tflite::MicroInterpreter(tflu_model, tflu_ops_resolver, tensor_arena, tensor_arena_size, &tflu_error);

But the available signatures for the constructors are:
MicroInterpreter::MicroInterpreter(const Model* model,
const MicroOpResolver& op_resolver,
uint8_t* tensor_arena,
size_t tensor_arena_size,
MicroResourceVariables* resource_variables,
MicroProfilerInterface* profiler)

MicroInterpreter::MicroInterpreter(const Model* model,
const MicroOpResolver& op_resolver,
MicroAllocator* allocator,
MicroResourceVariables* resource_variables,
MicroProfilerInterface* profiler)
