Subject: [PATCH v2 5/7] scripts: python: implement get or create frame
 function
Message-ID: <a5749b6a98928b2a8fa6c1dd1c54201334edb04b.1688585597.git.anupnewsmail@gmail.com>

The get_or_create_frame function is responsible for retrieving or
creating a frame based on the provided frameString. If the frame
corresponding to the frameString is found in the frameMap, it is
returned. Otherwise, a new frame is created by appending relevant
information to the frameTable's 'data' array and adding the
frameString to the stringTable.

The index of the newly created frame is added to the frameMap.
