Support for sorting parameters

**Is your feature request related to a problem? Please describe.**
The only sorting supported by this wrapper currently is `:runtime_sort?` which may be inefficient if the sorting is supported by the API.

**Describe the solution you'd like**
The ability to define and use `sort_with` and `order_with` properties in the endpoint definition

**Describe alternatives you've considered**
Currently I am using `:runtime_sort?`

**Express the feature either with a change to resource syntax, or with a change to the resource interface**
```elixir
endpoint :list_users do
path("/users")
limit_with {:param, "limit"}
sort_with {:param, "sortBy"}
order_with {:param, "order"}
# runtime_sort? true
paginator CustomPaginator
end
```
