Retrofit responses with a null body

[MovementSpeed]

Currently, when using Esito's Result with a network request that returns a null body (example: fun foo(...): Result<Unit, Throwable>), EsitoBodyThrowableCall crashes because it tries to get a non-null body:

private fun <T> Response<T>.toEsitoResult(): Result<T, Throwable> {
        return if (isSuccessful) {
            Result.success(body()!!)
        } else {
            Result.failure(HttpException(this))
        }
    }
