AttributeError: 'bool' object has no attribute 'lower'

[ZhymabekRoman]

Hello @s3rius! Thank you for creating taskiq.

I encountered an exception (something like AttributeError: 'bool' object has no attribute 'lower') with taskiq when attempting to use my custom SimpleRetryMiddleware. The problem occurred with the following code:

@taskiq_broker.task(retry_on_error=True)
async def _process_not_reached_deal(deal_details: BitrixDealResultData) -> Optional[bool]:

Unfortunately, I don't have the full traceback of the exception to provide for troubleshooting.

I've implemented a fix, and the code is now working correctly:

_LABEL_PARSERS: Dict[LabelType, Callable[[str], Any]] = {
    LabelType.INT: int,
    LabelType.STR: str,
    LabelType.FLOAT: float,
    LabelType.BOOL: lambda x: str(x).lower() == "true",
    LabelType.BYTES: base64.b64decode,
    LabelType.ANY: lambda x: x,
}

However, I'm not entirely sure if the boolean value conversion logic (lambda x: str(x).lower() == "true") is the most appropriate approach. I'd appreciate your thoughts on this implementation.
