Don't Mutate Function Input For Text

[peter-zhong-replit]

Confirm this is an issue with the Python library and not an underlying OpenAI API

• This is an issue with the Python library

Describe the bug

In general, it seems like a bad practice to mutate input parameters. However,

text["format"] = _type_to_text_format_param(text_format) does exactly this.

See peter-zhong-replit@1e949be for potential fix.

To Reproduce

call .parse twice with text given, but use the same variable for text, confirm the second time it's mutated and therefore will throw TypeError("Cannot mix and match text.format with text_format")
