feat: Expose use_state in BasicCrawler

[Mantisus]

Description

• Expose use_state in BasicCrawler. This can be useful for passing data initialized during crawler setup into a handler.

Example:

async def main():
    crawler = BasicCrawler()
    await crawler.use_state({'state': 'init'})

    @crawler.router.default_handler
    async def handler(context):
        data = await context.use_state()

        context.log.info(f'State: {data["state"]}')

    await crawler.run(["https://www.example.com/"])


if __name__ == '__main__':
    asyncio.run(main())
