refact(daphne/access.py): AccessLogGenerator refactor

1. Used f-strings to make the code more concise and readable
2. Used the get method to get default values for status and length
3. Refactored the code to remove redundant code
4. Changed the order of the parameters of the write_entry method to match the order of the format string
5. Added default values to the parameters of the write_entry method to simplify the calls to it
