DFU Library 1.10.0

New feature:

• Option to specify an initial delay before sending every data object has been added. Use setPrepareDataObjectDelay(long). By default, a 400 ms delay will be added before sending the 1st data object, but there will be no delay before the following objects. The delay set using this method will apply to all objects. The delay may reduce packet lose incidents, that would cause automatic switching to PRN =1.
