This is useful in CI/CD pipelines.

The chpharos itself is a shell function and cumbersome to use in CI scripts, you have to do something like bash -c "source /xyz/chpharos.sh; chpharos install 1.3.2 && chpharos use 1.3.2 && pharos up".

Directly downloading the binaries is also cumbersome.

The chpharos-exec is an executable, so you can just do: curl -s https://get.pharos.sh | bash && chpharos-exec -i 1.3.2 pharos up (you need to have CHPHAROS_TOKEN environment variable set)
