I'd like to add a package ada-lite-mode to ELPA; code attached. The
intent is to be a mode for Ada files that's easier to install than the
current ELPA ada-mode.

This can be used as-is, in which case all you get is reserved word
highlighting. Or it can be used with eglot and an Ada language server,
which gives many more features (some of which ada-mode does not have).

Installing the AdaCore ada_language_server is easier than installing the
executables for ada-mode; it can be done via Alire (https://alire.ada.dev/).
