## Added

- Added `Drop` implementations for streaming bodies to close streaming responses when the associated `StreamingBodyHandle` or `StreamingBody` goes out of scope. This allows client requests to finish while the Compute program is still running.

- Added `downstream_original_header_count`, which gets the original number of headers of the downstream request.

- Added `ResponseHandle::remove_header` and `RequestHandle::remove_header`, which can remove headers directly from handles.

## Changed

- Separated the low-level Compute bindings into a new, separately-versioned crate, in order to reduce the frequency of breaking changes for users of the `fastly` crate.
