Extends the Lwt_result_syntax with additional utilities for wrapping results produced by the protocol, i.e. Environment.Error_monad.tzresult, to tzresult Lwt.t values used in the tests.

The added utilities are binding operators. They use the same symbols as the ones from Lwt_result_syntax with an added @ character. This character symbolizes the ewrapping of the internal error monad type in a shell error.

wrap res maps the result type contained in res to a tzresult value.

let*@ x = m in f x is equivalent to let* x = wrap m in f x.

Mnemonic: @ "wraps" a protocol error in a shell error.

let*?@ x = m in f x is equivalent to let*? x = Environment.wrap_tzresult m in f x.

Mnemonic: @ "wraps" a protocol error in a shell error.

let+@ x = m in f x is equivalent to let+ x = wrap m in f x.

Mnemonic: @ "wraps" a protocol error in a shell error.
