Citrix-in-a-VM for DTCC onboarding

The Citrix package is a bit finnicky to install and is closed source / considered-insecure for our needs here at Obsidian. This flake 1) wraps the citrix_workspace package with a scraper that automatically downloads the tarball for you, and 2) provides Citrix-in-a-NixOS-Qemu-VM with a convenient init script that copies in your preferred .ica file to launch it with.

Usage of this repository implies you have read and accepted the Citrix EULA found here: https://www.cloud.com/content/dam/cloud/documents/legal/end-user-agreement.pdf

There is still the manual step of logging into myvdi.dtcc.com to download a fresh ICA file each connection attempt. We could look into automating this in the future; it's a bit more involved though.

Usage:

# Prompt for ICA file selection and launch the VM.
nix run
