add loguru logger object support

[PyRSA]

Fixed the issue that when using loguru.logger as the log output object, the log string was not formatted correctly for output

[PyRSA]

use logging

• code

import logging

from retry import retry

logging_logger = logging.getLogger(__name__)


@retry(tries=3, delay=0.5, max_delay=10, backoff=0.5, logger=logging_logger)
def test_logging_logger():
    def add(a, b):
        return a + b

    assert add(1, '2')

• out

TypeError: unsupported operand type(s) for +: 'int' and 'str' in __main__.test_logging_logger, retrying in 0.5 seconds...
TypeError: unsupported operand type(s) for +: 'int' and 'str' in __main__.test_logging_logger, retrying in 0.25 seconds...
...

use loguru

• code

from loguru import logger as loguru_logger
from retry import retry


@retry(tries=3, delay=0.5, max_delay=10, backoff=0.5, logger=loguru_logger)
def test_loguru_logger():
    def add(a, b):
        return a + b

    assert add(1, '2')

Although this doesn't meet Python best practices, the Loguru library becomes increasingly popular, and since loguru isn't compatible with logging it makes sense to adapt this lib for those type of logging libraries as well and make it more generic.
Thanks for your contribution!
