Feature

* Add client for SystemLink results API ([82](https://github.com/ni/nisystemlink-clients-python/issues/82)) ([`53f1188`](https://github.com/ni/nisystemlink-clients-python/commit/53f1188b4c4806819dbd20011c4b69d6f51487f9))

Fix

* Enable null value for results properties ([99](https://github.com/ni/nisystemlink-clients-python/issues/99)) ([`cba5106`](https://github.com/ni/nisystemlink-clients-python/commit/cba510629a142bffc8d9c5872d2f7a27bca2e8c3))

Feature

* Add and resolve query projection for products and specs respectively ([97](https://github.com/ni/nisystemlink-clients-python/issues/97)) ([`e9feff6`](https://github.com/ni/nisystemlink-clients-python/commit/e9feff6dc3e473dd34cbb53739f1c96eb7a8db0e))

Breaking

* Product and Specification models have been updated to support projections. - Product client changes-- - `models.Product` now defines all fields as Optional. - `ProductClient.create_product`'s `products` parameter is now typed as `models.CreateProductRequest` - `ProductClient.update_product`'s `products` parameter is now typed as `models.UpdateProductRequest` - Specifications client changes-- - `models.Specification` and `models.SpecificationDefinition` now define all fields as Optional. - `models.QuerySpecifications` has been renamed `models.PagedSpecifications` to better align to other clients. - `models.CreateSpecificationeRequest.specs` is now typed as `models.CreateSpecificationsRequestObject` instead of `models.SpecificationDefinition` - `models.UpdateSpecificationeRequest.specs` is now typed as `models.UpdateSpecificationsRequestObject` instead of `models.Specification` ([`e9feff6`](https://github.com/ni/nisystemlink-clients-python/commit/e9feff6dc3e473dd34cbb53739f1c96eb7a8db0e))
