Subject: [PATCH] Enable pipe-operators experimental feature by default

Uses extra-experimental-features to append pipe-operators after config
loading, so it's always enabled regardless of any user-configured
experimental-features setting.

The pipe operator (`|>` and `<|`) is used heavily in Tecnix/Tectonix
Nix expressions at Shopify.
