feat: add CLI and web interface

[not-lain]

CLI

the cli is built on top of typer so running atropos --help will give a list of all the valid commands, including install, list and delete

Web interface

for the sake of testing i have deployed this on my end at https://not-lain.github.io/atropos

to download an environment, you can simply run the following command,

## the --base-url  field automatically updates in case you are working locally or from github pages
atropos install answer_format_environment --base-url https://not-lain.github.io/atropos 

and to get a list of all the environments and where they are stored you can run

atropos list
