Simplified usage

Biggest release in a while!
As now with teamwalnut/graphql-ppx#48 we could simplify the API.

Thanks for everyone involved in this, special thanks @jfrolich who first proposed the changes to happen.

How it was

module GetAllPersonsConfig = [%graphql
  {|
  query getAllPersons($skip: Int!, $first: Int!) {
    allPersons(skip: $skip, first: $first) {
      id
      age
      name
    }
  }
|}
];

module GetAllPersonsQuery = ReasonApolloHooks.Query.Make(GetAllPersonsConfig);

let personsPerPage = 10;

[@react.component]
let make = () => {
  let skipRef = React.useRef(0);
  let (simple, full) =
    GetAllPersonsConfig.make(~skip=0, ~first=personsPerPage, ());

How it is now

module GetAllPersonsQuery = [%graphql
  {|
  query getAllPersons($skip: Int!, $first: Int!) {
    allPersons(skip: $skip, first: $first) {
      id
      age
      name
    }
  }
|}
];

let personsPerPage = 10;

[@react.component]
let make = () => {
  let skipRef = React.useRef(0);

  let (simple, full) =
    ApolloHooks.useQuery(
      ~variables=
        GetAllPersonsQuery.makeVariables(~skip=0, ~first=personsPerPage, ()),
      ~notifyOnNetworkStatusChange=true,
      GetAllPersonsQuery.definition,
    );

No more functors!
