### What is the problem this feature will solve?
I will be able to do this:
```javascript
const csvParsedStream = fs
.createReadStream('file.csv')
.compose(csvParse({ columns: false }));
const [columns] = await csvParsedStream
.take(1)
.toArray();
// This will now be empty and no data as take already consumed the stream
const parsed = await csvParsedStream
.map((row) => parseRowByColumns(row, columns))
.toArray();
```
Another example (I know I can use `[first, ...rest]` this is just an example):
```javascript
const a = Readable.from([1, 2, 3, 4, 5, 6, 7, 8, 9, 10]);
const [first] = await a.take(1).toArray();
console.log(first);
// [1]
const rest = await a.toArray();
console.log(rest)
// []
```
### What is the feature you are proposing to solve the problem?
Adding `closeStream` option to the `take` operator that with default value `true` that I could disable closing the stream
```javascript
const csvParsedStream = fs
.createReadStream('file.csv')
.compose(csvParse({ columns: false }));
const [columns] = await csvParsedStream
.take(1, { closeStream: false }) // Right now this would close the stream, but we give it an option to not
.toArray();
const parsed = await csvParsedStream.map((row) => parseRowByColumns(row, columns)).toArray();
```
### What alternatives have you considered?
Get the first value from stream as async itarator and rest
```javascript
let columns;
for await (const c of csvParsedStream.iterator<string[]>({ destroyOnReturn: false })) {
columns = c;
break;
}
const parsed = await csvParsedStream
.map((row) => parseRowByColumns(row, columns))
.toArray();
```
