Add Sigma Support for S1 PQ and Cortex

[rc-csmith]

Changes

• Add Sigma support for S1 PQ and Cortex products
• Update unit tests as necessary
• Add option to provide common.sigma_translation a list of YML-formatted strings or a list of files
  • Code does not support a mix of strings and files names so will throw and error and not do any processing
