See https://www.chegg.com/homework-help/questions-and-answers/see-following-instructions-write-code-python-add-imports-needed-class-rmsstream-rmsstream--q31074153 and the following instructions and write the code in Python:

# Add imports as needed class RMSStream: """RMSSTream  Streamer object for root mean square intensity in dB  Given an object of class AudioFrames  """   def __init__(self, frames): "RMSSTream - root mean square stream from an AudioFrames object"    def __iter__(self): "__iter_ - Return an object that iterates over RMS frame values"   # Implementation decision # You can return self and implement a __next__(self) in this class # or you can create and return an instance of an iteration class # of your design that supports __next__(self). In either case, the # __next__ method will return the next RMS value in dB rel. def shape(self): "shape() - shape of tensor generated by iterator"   # See descriptions in audioframes.py def size(self): "size() - number of elements in tensor generated by iterator"    def __len__(self): "__len__() - Number of frames in stream"
