KBL - Excel to CSV extractor

Keboola extractor, that converts excel to CSV based on input mapping criteria.

1. Set up the tables in the UI of input mapping in Keboola
2. Set up the configuration json in the following way:

{
  "parameters": {
    "S3key": "XXXXXXX",
    "S3secretKey":"XXXXXXXXX",
    "bucketName":"XXXXXXXXXX"
  }
}

3. The component will then take all the input tables, transforms them into .xlsx files and uploads to S3 accordingly to your json settings.
