Product option prices by customer group OpenCart Extension for 3.x

install.xml

<modification>
  <notes><![CDATA[
    This plugin is a conversion of https://www.opencart.com/index.php?route=marketplace/extension/info&extension_id=32403
    to work with OpenCart 3.x in OCMOD format.
    To use it, put this file into a ZIP file named "product-option-prices-by-customer-group.ocmod.zip"
    (the important part is the `.ocmod.zip` extensions) and install it in your OpenCart.
    YOU WILL ALSO NEED TO RUN THE FOLLOWING DATABASE COMMAND MANUALLY to create the extra column:
    "ALTER TABLE product_option_value ADD COLUMN customer_group_id INT NOT NULL DEFAULT 0;"
