Use $XDG_DATA_HOME instead of $HOME

It would be nice if you used $XDG_DATA_HOME as the directory where to save the data which you now save in $HOME/.xcv

Here is a write up of the problems of dot files https://wiki.gnome.org/Initiatives/GnomeGoals/XDGConfigFolders with links on how to fix it.

This should be done. Though macOS does not support xdg specification, and it seems that the author is a macOS user

I rewrote this script this morning, added the support for XDG specification, welcome to take a look:)
