Add an optional maxPerAddress parameter in the marketplace

[damienen]

Requirements:

1. Whenever someone lists they can specify an optional maxQuantity parameter which limits how many of those NFTs an address can buy
2. If they don't send such a parameter, the maxDefaultQuantity is set to be used instead

Should be delivered with this PR: Itheum/sdk-mx-data-nft#129

Seems like you added a maxQuantity per TX, but a max quantity per ADDRESS is needed. (see updated descriprition above as well)

Code reviewed. Looks good. But to be noted: it's a breaking changes for the addOffer endpoint

pub struct OfferOut<M: ManagedTypeApi> {

We should return how much the user can buy on his address for each offer in offer out (not how much IN TOTAL, but how much considering what he has bought so far)

Change should be reflected in the SDK as well

Solved. Closing
