Appending of image without prior reshaping

[vstadnytskyi]

See issue vstadnytskyi/intel-realsense-devices#17 for details. The circular buffer numpy library needs to be modified. Also, see exact code that can reproduce the error.

The proposed solution:

1. check the dimensionality of incoming data. If data is one dimension smaller, assume that first dimension is 1. If dimensionality the same, append as it is.

• modify

  circular_buffer_numpy/circular_buffer_numpy/circular_buffer.py

  Line 50 in 7c039cd

  def append(self, data):

• add test that would check this behaviour
