Support directories in referenced_filenames for rules #4276
Description
Sometimes references to license files are in terms of specific directories instead of one/multiple filename/paths.
See for example: https://github.com/avnet-iotconnect/iotc-azurertos-sdk/blob/0e6fe7c9ede4f97a81203eafc930577906736455/README.md?plain=1#L157
A simple way to support this would be to have simple glob patterns like:
referenced_filenames:
- azrtos-licenses/*
And check if there are glob patterns in the referenced_filenames and only then process these, otherwise fallback to the simple filename based processing which should be much faster.
