Been using ShopifySharp for a while now and suite happy with it!

Today I ran into unexpected behavior when attempting to update a PriceRule (but the behavior is true for all entities). I want to reset the EndsAt date from a value to null (no end date applies). The update doesn’t actually tale effect because EndsAt is never sent to Shopify. This is because the Json serializer is instructed to ignore nulls.

How would one go about updating a value to null with ShopifySharp?

Perhaps it would be useful to add a parameter to Update to ignore nulls or not?
