Cloudflare Data Connector - Chunking of file causing an exception

[katerobson08]

Describe the bug
**One of our customers has an issue with the Cloudflare function app falling over on files larger than 2MB. The customer file was 4.2MB.

The function app raises the following exception:**

Exception: HttpResponseError: Download stream interrupted.
Stack: File ""/azure-functions-host/workers/python/3.8/LINUX/X64/azure_functions_worker/dispatcher.py"", line 402, in _handle__invocation_request
call_result = await self._run_async_func(
File ""/azure-functions-host/workers/python/3.8/LINUX/X64/azure_functions_worker/dispatcher.py"", line 654, in _run_async_func
return await ExtensionManager.get_async_invocation_wrapper(
File ""/azure-functions-host/workers/python/3.8/LINUX/X64/azure_functions_worker/extension.py"", line 147, in get_async_invocation_wrapper
result = await function(**args)
File ""/home/site/wwwroot/AzureFunctionCloudflare/main.py"", line 69, in main
await asyncio.gather(*cors)
File ""/home/site/wwwroot/AzureFunctionCloudflare/main.py"", line 148, in process_blob
async for chunk in blob_cor.chunks():
File ""/home/site/wwwroot/.python_packages/lib/site-packages/azure/storage/blob/aio/_download_async.py"", line 151, in anext
self._current_content = await self._iter_downloader.yield_chunk(chunk)
File ""/home/site/wwwroot/.python_packages/lib/site-packages/azure/storage/blob/aio/_download_async.py"", line 62, in yield_chunk
return await self._download_chunk(chunk_start, chunk_end - 1)
File ""/home/site/wwwroot/.python_packages/lib/site-packages/azure/storage/blob/aio/_download_async.py"", line 105, in _download_chunk
chunk_data = await process_content(response, offset[0], offset[1], self.encryption_options)
File ""/home/site/wwwroot/.python_packages/lib/site-packages/azure/storage/blob/aio/_download_async.py"", line 27, in process_content

I got around this by changing the MAX_CHUNK_SIZE_MB parameter to 5MB (to be bigger than the file so that it didn't try to chunk it)

To Reproduce
Steps to reproduce the behavior:

1. Create a file larger than 2MB in storage account
2. Run Cloudflare function app
3. Fails with exception produced: Exception: HttpResponseError: Download stream interrupted.

Expected behavior
I would have expected the file to have been proccesed and then deleted.
