Create a night-log for a given list of input frame.
This log lists, for each frame * filename * type of observation: bias/dark/flat/science * binning * filter name * exposure time * Object/target name as specified during the observation (this is not necessarily
the real name of the target, rather what the user entered)
The output of this file is compatible with the file-list requirements of, for example, podi_makecalibrations.
