Simplify usage of `cpackget`

[ReinhardKeil]

The Problem To Be Solved To download latest packs the user it today request to use the update-index command that actually updates all *.pdsc files in the .Web folder.

For getting information about latest packs the index.pidx file should be sufficient. In fact Keil Studio Desktop can obtain all other information (about devices, packs, etc) utilizing web services which removes the need for a local copy of all *.pdsc files.

Suggest A Solution Can we review the usage of the .Web folder?

cpackget update-index --sparse shall not update any pdsc files in the .Web folder.

Note:

• cpackget update-index only pdsc files that are already present in the .Web folder will be updated.
• cpackget update-index --all-pdsc-files ensures that all pdsc files will be download if the file is not present or out-of-date.
• cpackget init https://www.keil.com/pack/index.pidx by default does not download any pdsc files.
• cpackget init https://www.keil.com/pack/indexpidx --all-pdsc-files will download all pdsc files listed in index.pidx
