SSL Error causing crash when fetching image sets.

[andrewtremblay]

To fix, I've adjusted fetchSetImages.py

import os
+ import ssl

+ context = ssl._create_unverified_context()

def fetchSetImages(setcode):

    if (setcode+'.images') not in files: # if .images file doesnt exist
        print(setcode +'.images','file not found, generating from gatherer now')
        set = cardset(setcode)# call card_set_json to get image URLs
        for i in range(len(set.uids)):# fetch all card images from URLs
            url = set.imgurls[i]
            if (url != None):
+                url_response = urlreq.urlopen(url, context=context)
                img_array = np.array(bytearray(url_response.read()), dtype=np.uint8)
                img = cv2.imdecode(img_array, -1)
                imgdict[set.uids[i]] = img
                print(i)
                

Ideally we would need to securely download the images from the https urls, but I'm not sure if that's the responsibility of this repo or MTG json not providing the correct URL.
