[djjuhasz]

Fixes #60

• Add a "fileFormat" section to the preprocessing config file
• Add a "AllowlistPath" config option to the "fileFormat" section
• If no "AllowlistPath" is configured, then file format validation will be skipped
• Add an allowed format CSV file to the dev and enduro kube configs
