Description

## New Feature

Support [interpolate-hcl](https://docs.mapbox.com/mapbox-gl-js/style-spec/expressions/#interpolate-hcl) and [interpolate-lab](https://docs.mapbox.com/mapbox-gl-js/style-spec/expressions/#interpolate-lab) expression operators.

## Why

To have parity with Mapbox GL JS that supports these operators and be able to share the same style between a web platform and an iOS application.
Right now, consuming a style using one of these operators results in a black layer on iOS.

Research direction

No files, tests, or entry points are named. Read the linked Mapbox expression specifications, then locate the existing interpolation expression handling and its tests in the iOS project. Done means interpolate-hcl and interpolate-lab styles are supported on iOS instead of producing a black layer.
