Woocommerce-admin: Fatal error when WooCommerce Admin and WooCommerce Measurement Price Calculator are active

1. Activate WooCommerce Admin and WooCommerce Measuerement Price Calculator.
2. Go to _Products_ > _Add New_.
3. Notice a fatal error occurs:
   > Fatal error: Cannot declare class WC_Settings_Products, because the name is already in use in /var/www/html/woocommerce/wp-content/plugins/woocommerce/includes/admin/settings/class-wc-settings-products.php on line 0

The error happens when we preload the data endpoints in WC_Admin_Loader:

I think the fix for this will need to live in the WooCommerce Measuerement Price Calculator plugin - it's directly including the class-wc-settings-products.php file if it needs the WC_Settings_Products class rather than using core WC's loader method WC_Admin_Settings::get_settings_pages().

I'll open a PR on the plugin's repo.

Looks like they have a fix coming in their next release - thanks @jeffstieler for opening the PR and helping with the fix!
