Flake8cleanup

[evelynmitchell]

This patch suppresses or fixes all the flake8 whitespace errors.
It also adds at the top level a .flake8 config which will suppress all the line too long warnings.

There are a few flake8 warnings I didn't know how to fix:

./auto_swarm_builder.py:14:1: F811 redefinition of unused 'logger' from line 1
./tests/agents/test_agent_logging.py:7:1: F811 redefinition of unused 'parse_and_execute_json' from line 4
./swarms/utils/calculate_func_metrics.py:12:1: F811 redefinition of unused 'logger' from line 7
./swarms/structs/agent.py:1795:37: E203 whitespace before ':'
./swarms/tools/py_func_to_openai_func_str.py:22:1: F811 redefinition of unused 'get_args' from line 5
