ConvertCSVToRecords - Add ability to ignore first row headers in CSV and provide alternative api names

[RomanTheCube]

This action is so incredibly useful however in my opinion, it would be so much more broadly useable if one change were added, which would allow you to essentially choose if you want to use the CSV's first row headers as the api names, OR you can ignore that row in the file and use api names that the user provides.

Suggestion:

1. Add boolean option "Ignore first row column headers"
2. Add text input field for Comma Separated List of field api names, and use these instead of file first row headers
