What's Changed
* Implemented `Sms.get_sms_list_pdu` and `Sms.send_sms_pdu` for PDU sms sending/receiving (untested since my device does not support these)
* Implemented `Device.mode` that allows to set device mode specified in `enums.device.ModeEnum`, this allows to enable telnet AT command interface on port 23 see https://github.com/Salamek/huawei-lte-api/wiki/AT-Command-interface-Telnet and https://github.com/Salamek/huawei-lte-api/blob/master/examples/toggle_telnet.py for more info
