Could you please update files to match odoo V13 ?

Hello,
first of all thanks for your work.
I'm trying to use this repo against latest odoo version and some models seems to have changed (product.supplier.info , product.attribute.line)
I do understand that you provided everything needed to do this by myself but it's gonna take me ages as I I'm new to odoo and python - so just asking :)
Cheers
