Initial support for upgrading firmware of the MiBand.
This release seems to be working quite well with respect to the firmware upgrading itself. The user facing part needs more work. In order to update the firmware one has to: - open a file ending with .fw - switch from the firmware upgrade activity to the main one - connect to the miband - return to the firmware upgrade activity - press the "install" button (that became active when the device connection was established) Caveats: There are almost no check wrt. the integrity of the firmware files.master
