Request: Add gap_parse_service_data to mjs

[danielknox]

mgos_bt_gap_parse_service_data() has recently been added to the BT-Common C library. Could a wrapper be added to the MJS library, with example of use? The benefit of this would allow users to see if an advertising device has a service uuid that they might be interested in before attempting to open a connection to a device. The current example connects to device based on local name (many devices do not use local names) and then scans for the services that device offers.

this makes sense, and if you send a PR it will happen sooner.
you can use other wrapped functions in this library as a guide how to do it.
