Updated handling of Shopify Price & Compare Price

Updated logic:

Shopify “Compare Price” is the default Base Price in CSV, if it is empty, then Shopify “Price” is the Base Price.
 
If “Compare Price” is empty, & only “Price” exists, the Base Price in the CSV is that value and Sale Price is null.

If “Compare Price” is greater than the “Price”, then Base Price in the CSV is “Compare Price” and the Sale Price in the CSV is “Price”.

If “Compare Price” and “Price” are equal, the Base Price will inherit the equal value & Sale Price is null.
