Replace threading.Lock with asyncio.Lock when batching to avoid deadlocks

[tsmith023]

• Changes all threading.Lock in async def fns to asyncio.Lock to avoid blocking the event loop
• Changes all time.sleep() in async def fns to asyncio.sleep() to avoid blocking the event loop
• Improves logging when errors occur during the batching logic
• Uses BatchObject instead of _BatchObject in ErrorObject and BatchReference instead of _BatchReference in ErrorReference for easier usage of errors

Closes: #1332
