COMPASS install command

[ppinchuk]

Add a compass install command that runs installation script for other packages, but also crucially downloads the ordinance database to user local cache for use

I think there are two tasks here:

• A shell script that downloads COMPASS binary (As @ppinchuk pointed before, similar to pixi)
• The functionality to download, use, and update a local database. This part might be better done through the COMPASS binary itself. Assuming one can easily install the binary, that command line should have a subcommand to maintain the data.

Yea I'm perfectly fine if the command to download and maintain the database is part of the CLI binary itself. I only gave the pixi script as an example of how it could be done :)
