fix(Request): forward Buffer & string payloads again

[pakerfeldt]

What happened

PR #74 added a type‑safety guard to src/nodes/Request.ts:

const _send = (Result: UnifiResponse) => {
    self.send({
        payload: Result,
        inputMsg: msg,
    })
}
if (!Buffer.isBuffer(data) && typeof data !== 'string') {
    _send(data)
}

The guard works for JSON endpoints, but it silently drops every UniFi endpoint that returns raw bytes or plain text — most notably the Protect /snapshot thumbnails that are requested with responseType: 'arraybuffer'.
Since those thumbnails are delivered as Node Buffers, downstream flows never see them.

What this PR does

• Restores the pre‑1.1 behaviour for binary and text payloads.
• Keeps the stricter UnifiResponse typing for all JSON endpoints.
• Collateral cleanup: Removes the console.log (moving the type printed into another debug log)
