Fix attribute names

[linhsolar]

Pls. use well-defined attribute names in qoa language, no space in the attribute name, e.g. (dataquality.py)

 results = {}
 results["Total Errors"] = error_df.to_numpy().flatten().sum()
 results["Error Ratio"] = 100*error_df/total_count

Attribute name Updated

still the problem exists: if isinstance(image,PIL.JpegImagePlugin.JpegImageFile) or isinstance(image,PIL.Image.Image):

qoaLogger.debug(dir(image)

    quality["Image Width"] = image.width
    quality["Image Height"] = image.height
    quality["Image Size"] = image.size
    quality["Color Mode"] = image.mode
    quality["Color Channel"] = len(image.getbands())

Spaces removed

this issue has not be completely solved: check mlquality.py.

I suggest to keep the same way whenever we introduce a new attribute.
