- Revert changes to get_status() and do not deprecate memory feature for now. Further testings will be performed in the following days and this change will be re-implemented in the next release.

- Switch from dicttoxml to dicttoxml2
- Add a small delay between different requests

- Deprecate get_status memory parameter: Fixes 9
- Workaround dicttoxml issue with Python 3.10

- Close the socket on errors
- Do not include the memory feature by default

- Use again the sequence number when sending request list
- Raise a ConnectionError when the alarm reply is wrong

* Do not reuse previous sockets to reduce the probability of receiving an unexpected reply
