Enable "allow_subproduct_substitution" on consume endpoint

Expected behaviour: Consumption against parent products will use sub-products' stock when substitution is allowed.

Actual behaviour: Consumption against parent products returns HTTP 400 and we can't set "allow_subproduct_substitution" to use sub-products' stock.

This is causing the following issues downstream in the grocy / Home Assistant custom component: custom-components/grocy#182

Possible solution

Bernd points out that we should allow substitution: grocy/grocy#1767 (comment)

So, I think we need to update the POST body with "allow_subproduct_substitution", possibly defaulted to False in the code here:

pygrocy/pygrocy/grocy_api_client.py

               amount: float = 1,

               self._do_post_request(f"stock/products/{product_id}/consume", data)

What do you think?

	def consume_product(
	self,
	product_id: int,
	amount: float = 1,
	spoiled: bool = False,
	transaction_type: TransactionType = TransactionType.CONSUME,
	):
	data = {
	"amount": amount,
	"spoiled": spoiled,
	"transaction_type": transaction_type.value,
	}

	self._do_post_request(f"stock/products/{product_id}/consume", data)
