Add inference download

[grmpfhmbl]

Describe the solution you'd like
There should be an inference download command to download the results and store them in output_path. When multiple inferences match, subdirectories will be created.

Filter options: id, knowledgebase_id, factbase_id (all multi)
Download options:

• result (multi) to specify the result names. Default: all results will be downloaded.
• include_qgis_project (true/false) to indicate wether to download the Q_GIS project. Default: true

sen2cli inference download --id=123 --id=321 <output_path>
sen2cli inference download --id=123 --id=321 --include_qgis_project=TRUE/FALSE --result="result1" --result="greeness_no_cloud"
