Make reqwest an optional dependency
This adds a feature to the Cargo.toml to be able to control if dhall depends on reqwest. This makes it possible to build dhall-rust for any arch (not just wasm32) without depending on reqwest. To disable reqwest as a dependency, we can now use `default-features = false` when adding the dhall dependency. Closes #169
