[RFC] stock_barcodes_gs1: add AI 310 barcode value

Hello,

according current implementation of stock_barcodes_gs1 addon, only (01, 02, 10, 37) AIs are implemented. For product quantity, 37 is used, but it should be altered via _process_product_qty_gs1 hook method within main processing method (https://github.com/OCA/stock-logistics-barcode/blob/14.0/stock_barcodes_gs1/wizard/stock_barcodes_read.py#L91).

For those who e.g. work with net weights as quantity unit, 310x (like 3102, 3.50 kg => 00350) is usually used, that we've tested that is successfully filled in base_gs1_barcode decode method as 310 key.

In my case I'd simply solve if this piece of code:

https://github.com/OCA/stock-logistics-barcode/blob/63a0576ccce0fbffa04ca8765e4622c0c92eba77/stock_barcodes_gs1/wizard/stock_barcodes_read.py#L67C9-L67C21

both 37 and 310 should be accepted. But, if this proposal shouldn't be a good approach (this could be inconsistent with current implementation and could be rejected), I cannot use hook method _process_product_qty_gs1 because barcode_decoded dict with all values (including my desired 310 alternative quantity) is not available for hook method.

Why should be the proper approach for this?

Create a simply PR accepting 310 quantity when 37 is not filled (enough for my scenario, and immediately available for everyone).
Pass barcode_decoded to hook method, so me and other people could make our custom implementation with another addon (and try to call it even if product_qty is not initially filled).

I could make a PR with the finest solution.

@sergio-teruel @etobella what do you think?

Well, IMO, I see another option 🤔

Add the hook of product_qty here:

stock-logistics-barcode/stock_barcodes_gs1/wizard/stock_barcodes_read.py

Line 89 in 63a0576

if product_qty and package_barcode:

We should do that in order to pass the product and package to the hook, that would be cleaner and we could decide to use 310 when the unit of the product is of a weight kind. WDYT?

Hi.
Why not add the hook here:

https://github.com/OCA/stock-logistics-barcode/blob/14.0/stock_barcodes_gs1/wizard/stock_barcodes_read.py#L67

Create a method to get product_qty from (37) by default if exists in barcode else get from 310 or 330 (net and gross).. if three keys exist in the same scan read ... mnhhuuuu I don't know jaja
