How to upload image in the create API ?

[numerogeek]

Hi !

I am tryin to use the $apiClient->product()->create() with an array of data, including images.
It appears that here https://github.com/FriendsOfApi/sylius-api-client/blob/master/src/RequestBuilder.php#L60 you check if the $body is an array.

It's always an array, because of here https://github.com/FriendsOfApi/sylius-api-client/blob/master/src/Api/HttpApi.php#L76 you create a json from params.

So we can't send files I guess ?
We should be able to chose not to convert params in json, what do you think ?
