change the current implementation of quantization table matching

[Omoshirokunai]

Currently the quantization tables gotten from an image is directly compared with a hard coded list of photoshop tables, this was done for demo purposes and not really reliable/bugged.

A possible solution would be to have the list of tables in a format (.txt) outside the quantization_table.py file like done in the quantable_class folder that the quantization_table.py file can use to search and match the tables extracted from the image.
