qmpfw: Quick Mesh Project legacy firmware generator (deprecated)

Adds a new way to generate/store the configuration files for each target:
There are profiles (such as ath-qmp-small-node) which are shared between all similar kind of devices (i.e ubiquiti devices)
And individual configurations (optional) which can be used to specify extra options for the device

Adds new target for t-mr3040 bmx6 testing
