Add an APDU backend for MBIM devices. The MBIM device path can be passed via the MBIM_DEVICE environment variable. We'll default to /dev/cdc-wdm0. By default we will not operate through the mbim-proxy. Set MBIM_USE_PROXY to 1 to enable this. Like QMI devices, use UIM_PORT to select the active SIM slot. Tested on Semtech EM9191 and EM7590, and Quectel RM520N-GL. resolve #94 Signed-off-by: Frans Klaver <frans.klaver@vislink.com> Co-authored-by: Frans Klaver <frans.klaver@vislink.com>
