fetchTypeHandler - access to rowset meta data

[sosoba]

1. Describe your new request in detail

Currently fetchTypeHandler receives the metadata of a single column in its only parameter. One of the possibilities offered by this plugin is changing the name of a column (field in the result object). Ex.:

fetchTypeHandler: (columnMetaData) => {
  columnMetaData = columnMetaData.toLowerCase();
}

To perform this safely it would be useful to have knowledge of all the result columns. Ex.

fetchTypeHandler: (columnMetaData, rowsetMetaData) => {
  const newName = columnMetaData.toLowerCase();
  if (rowsetMetaData.every(({name}) => name !== newName)) {
    columnMetaData = newName;
  }
}

I would like to propose adding a second argument to handler.

2. Give supporting information about tools and operating systems. Give relevant product version numbers
   6.8.0
