You can use `logger.set_custom_logger` function to set your own logger now.

When python3.9 or above is being used, annotations `list[str]` can be used in your controller's parameters.

example:

pythone
route("/arr")
def arr(arr: list[str]):
return {"code": 0, "message": f"{arr}"}

1. When `Content-Length` and `Tranfer-Encoding` headers are bote omitted, `read` and `read_to_end` method will always return b''
2. `read(-1)` will always return bufferred data now.

Rename from `python-simple-http-server`, move some modules to separated projects.
