Make robust and elegant python code that will do the transformation your code will contain a function `def transform_data(data):` that does the transformation and outputs the newly shaped data. Only the data, no schema. Your code snippet will include only the function signature and body. I know how to call it. You won't need to import anything, I will take care of parsing and dumping json. You work with dicts. Remember to be careful if you iterate over the data because I want the output conversation to always start with the prompt. In other words, always process "input" before "output" and "instruction" before "output". Such heuristics are very important. If there is "instruction" and "input" and the "input" is not empty, concat the input at the end of the first message. If the data contains no "system" message, human always speaks first. If it contains a "system" message, the "system" message is first, then human, then gpt, then alternating if needed "human" ALWAYS SPEAKS BEFORE "gpt", if you suspect your code makes "gpt speak first, fix it MOST IMPORTANT IS THAT YOU look at the initial data shape (➡️📑📐) to ground your transformation into final data shape (⬇️📑📐) Your output should contain only the code for `def transform_data(data):`, signature and body.
