comand Start-FinopsCostExport without -Format

[vrondan1983]

Hello, im using powershell module FinopsTollkit , and its ok , but when we need to create an export , does not exist the parameter "-Format" to select CSV or Parquet , it creates the export and it choose by default CSV and i would like to use Parquet.

I think it would be great if you add that option .

Good call, we are missing this in New-FinOpsCostExport. Created #1074 to track this.
