Function brane_cli::utils::get_packages_dir

pub fn get_packages_dir() -> Result<PathBuf, UtilError>

Edited: Changed to return UtilErrors.

Returns the general package directory based on the user’s home folder.
Basically, tries to resolve the folder ’~/.local/share/brane/packages`.
Note that this does not mean that this directory exists.

Returns
A PathBuf with an absolute path to the packages dir, or an UtilError otherwise.
