use `pump(zipStream, writeStream)`, the zip file at disk is nested one level more

[WormGirl]

for example;
zip file: upload.zip include a foo.json, then upload it use stream, when i get the stream at server. and do this;

 const ctx = this.ctx;
 const stream = await ctx.getFileStream();
 const target = path.join(this.app.baseDir, 'app/upload', 'demo.zip');
 const writeStream = createWriteStream(target);
pump(stream ,writeStream )

the file render at disk actualy is demo.zip inclued upload -> foo.json. if I do this. it will be normal

 const ctx = this.ctx;
 const stream = await ctx.getFileStream();
 const target = path.join(this.app.baseDir, 'app/upload', 'demo.zip');
 const writeStream = createWriteStream(target);
 stream.pipe(writeStream);
 stream.on('finish', () => {
     stream.close();
 })

Doesn’t sound like a pump issue. Pump just pipes stream together. Maybe the zip thing is using a custom stream impl?

In anycase feel free to send a minimal runnable testcase with as few deps as possible and I’ll take a look
