"""take_image: The function will create a Operating System timestamp variable (OS_time), configure
the 2 IRCSP cameras to take an image (image1 & image2) and store the FPA temperatures
(temp1 & temp2) into an HDF5 File format with a unique naming convention.
Parameters:
filename - the filename of the HDF5 file.
Returns: HDF5 file with 2 FLIR Boson Images, 2 FPA Temperatures & OS_time string.
