csv-parser fails when given a stream from Stream instead of fs

[venya02]

• Operating System: Windows 10
• Node Version: 14.17.1
• NPM Version: 6.14.13
• csv-parser Version: 3.0.0

Expected Behavior

Creating a Readable stream and piping it into the parser should result in parsed csv data

Actual Behavior

internal/streams/readable.js:623
  throw new ERR_METHOD_NOT_IMPLEMENTED('_read()');
  ^

Error [ERR_METHOD_NOT_IMPLEMENTED]: The _read() method is not implemented
    at Readable._read (internal/streams/readable.js:623:9)
    at Readable.read (internal/streams/readable.js:462:10)
    at maybeReadMore_ (internal/streams/readable.js:610:12)
    at processTicksAndRejections (internal/process/task_queues.js:82:21) {
  code: 'ERR_METHOD_NOT_IMPLEMENTED'
}

How Do We Reproduce?

const Stream = require('stream')
const readableStream = new Stream.Readable()
const csv = require('csv-parser')
const fs = require("fs")
const results = [];

fs.createReadStream('csvTest.csv')
    .pipe(csv())
    .on('data', (data) => results.push(data))
    .on('end', () => {
    console.log(results);
    // [
    //   { NAME: 'Daffy Duck', AGE: '24' },
    //   { NAME: 'Bugs Bunny', AGE: '22' }
    // ]
    });
    
readableStream.push(`example,csv,data
    line,two,is
    not,needed,but
    I,made,one
    anyway,0,1`)

readableStream.pipe(csv())
  .on('data', (data) => results.push(data))
  .on('end', () => {
    console.log(results);
    // [
    //   { NAME: 'Daffy Duck', AGE: '24' },
    //   { NAME: 'Bugs Bunny', AGE: '22' }
    // ]
  });

csvTest.csv

both methods of creating a stream should result in the exact same output, as they have the exact same input.

Not sure if you still have the issue, but after pushing your actual data, you should also push null to the readable stream like such: readableStream.push(null).
