Ublox

-------------------

Added
^^^^^
* Timeouts to reads
* Better logging to find problems in threaded environments.
* Better exception descriptions.

-------------------

Changed
^^^^^^^
* Callback handling. Apparently it got object referencing problems when running
multiple threads using and instance of the module class.

Fixed
^^^^^
* Small bug when a UDP message is not received we parsed and empty response.

-------------------

Added
^^^^^
* Added functionality to read data from UDP sockets.
* Added interface for socket.recvfrom() to socket class.
* Small wait time on writes not to block interface.
* Current RAT information
* Possibility to set socket in listening mode


Changed
^^^^^^^

* callback registration process

--------------------

Added
^^^^^
* Arg to specify if the module is roaming or when connecting specify if roaming so that we know what to expect in the connection status.
* capture_urc flag to _at_command(). So that it is possible to collect the URCs before the OK response.
* Added the UbloxSocket and UDPSocket classes to be able to handle sockets independent from module.

Changed
^^^^^^^
* Removed operators name and map. Now you need to specify the operator with its MNO_ID. Swedish Telia is for example 24001.
* Renamed eps_reg_status to registration_status. Even if it does not follow the naming in the ublox manual it is clearer in the code what it is.
* create_socket now returns a UbloxSocket subclass.

------

Added
^^^^^
* Better support for R412.
* errors for AT commands and module errors will throw python exceptions.
* setting bands on r4 modules.
