Tippecanoe helm chart

Helm 3 chart for Tippecanoe. The chart setups a Kubernetes CronJob where you can specify how often it should run and what arguments Tippecanoe should be called with. The Helm chart also allows you to run a pre-job using GDAL or your own configuration. This can be enabled using the Chart configurations.
