* remove telemetry
* no full git clone
* add intelhex as required
* no core packages
* add `rich_click` as pip dependencies
* remove advertisings
* add intelhex as required
* install scons and Pio home from github
* replace "get_core_package_dir" for piohome and pioremote
* Avoid working with detached / non-existent git branches when checking for updates
b/c we can't use `pull` anyway in that situation
Otherwise, ask for the specific branch via `refs/heads/{branch}` and
also fail when it is not available
* Update vcsclient.py
