## Added

  `set_body_text_html()` convenience methods which set the body contents along with their respective
  content types.
- Added `Response::see_other`, `Response::redirect`, and
  `Response::temporary_redirect` builders to support building a redirect
  response and its `Location` header all at once.
- Added `SendError::root_cause` and `SendErrorCause` to describe specific upstream request failure causes.

## Deprecated

- Deprecated `with_body_str()` and `set_body_str()` methods in favor of `with_body_text_plain()` and
  `set_body_text_plain()`.

## Changed

- `RequestHandle::send`, `RequestHandle::send_async`, and `Requestandle::send_async_streaming` now return a specific `SendErrorCause` on errors, replacing an `anyhow::Error`.
- `select_handles` now returns a specific `SendErrorCause` on errors, replacing an `anyhow::Error`.
- `PendingRequestHandle::poll` and `PendingRequestHandle::wait` now return a specific `SendErrorCause` on errors, replacing an `anyhow::Error`.
