    A class to hold an input observation and associated metadata

    Attributes:
        image (Any): 
            The image associated with the observation.
        latitude (float): 
            The latitude where the observation was made.
        longitude (float): 
            The longitude where the observation was made.
        author_email (str): 
            The email of the author of the observation.
        date (str): 
            The date when the observation was made.
        time (str): 
            The time when the observation was made.
        date_option (str): 
            Additional date option for the observation.
        time_option (str): 
            Additional time option for the observation.
        uploaded_filename (Any): 
            The uploaded filename associated with the observation.

    Methods:

            Returns a string representation of the observation.
        __eq__(other):
            Checks if two observations are equal.
        __ne__(other):
            Checks if two observations are not equal.
        __hash__():
            Returns the hash of the observation.
        to_dict():
            Converts the observation to a dictionary.
