Implementation for sensors services

Hi, I'm currently trying to implement support for the sensor services over QMI so I can talk with the sensors which are on the aDSP on the Fairphone 2 (Snapdragon 801 / msm8974).

There seems to be a "main" service on service id 256 (0x100), a power management one at 257 (0x101), a debug one (which just has two 'indication' methods for debug string and debug log) at 263 (0x107), a service for controlling the debug service(?) at 264 (0x108) and another one which has some weird methods at 269 (0x10D). I'll be looking into implementing the first two because the others don't look too useful for now.

I'm currently having the problem: error: couldn't create client for the 'snsmgr' service: QMI protocol error (31): 'InvalidServiceType' I'm fairly sure the service id is correct as I've seen these ids before with qrtr-lookup (from https://github.com/andersson/qrtr)

And sorry if I'm confusing some terms, QMI is still a bit new to me :)
