DISCO_L496AG with BG96 Cell

Hi,

I have an ST DISCO_L496AG with Quectel BG96 modem connected via the ST Mod+ connector. From what I can find this board is supported by MBED as well as the BG96. Does a working example exist for this combination? The main page for the ST DISCO_L496AG doesn't list one however the MBED library I DL'ed does seem to mention one C:\..\mbed-os\components\cellular\COMPONENT_STMOD_CELLULAR.

When I attempt to build and run the example per the README.md, the project compiles OK, but I receive an assertion failure on execution. It appears the network interface may not be defined correctly?

I figured the problem out. I was building against Mbed v5.13 and needed to build against master since support for this component won't be officially released until v5.14.
