As this Plugin is not under heavy development i tried a little and made the following solution for me, for now:

Overriding the signale.d.ts types file by adding another with the following content:

import { WriteStream } from "fs";
import { SignaleOptions } from "signale";

declare namespace signale {

    interface SignaleOptionsX extends Omit<SignaleOptions, 'stream'> {
        stream?: NodeJS.Process.stdout | WriteStream | WriteStream[];
    }
}

declare const SignaleOptionsX: signale.SignaleOptionsX;

export = signale;

In my class then import { SignaleOptionsX } from '../../types/signale'; and changing SignaleOptions to SignaleOptionsX.

Now

...
stream: [
     process.stdout,
     this.logFile
]
...

Works for me again. Formatting isnt nice, but at least i dont get an error by typescript.
