UploadDirectory: use sub-folder name as source

[dadokkio]

Hi, we are using a custom script to download and keep updated yara rules from different github repos. Each repo is stored in particular sub-folders under the main folder that we want to bulk upload in YaraGuardian with the UploadDirectory command. The actual options are:

• bulk import everything having a single source option for everything
• import each sub-folder separately

Can be useful to add an option the the command that permit to use sub-folders name as source?
