Option to load data from binary file

[szkocot]

I was asked to convert binary dump file from cms50d+ to CSV format and I soon discovered this wonderful project, that helped me a lot. Then I realized, that there is no possibility to read data from a binary file that I got. The firmware version of the device was v5.1, but it seemed compatible with implementations in this code.

I was able to change the data source to file and there's the implementation: szkocot@51e5cdf

I am not sure if can be integrated into this project smartly, but in case someone has a similar case it might help.
It was tested on 6 recordings and 5 of them were successful and one had synchronization issues.
