Citrix-in-a-VM for DTCC onboarding

DTCC onboarding process requires you to access a remote Windows desktop via Citrix Workspace.

The Citrix package is a bit finnicky to install and is closed-source and considered insecure for our requirements 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 optionally copies in your preferred .ica file to launch it with. If you choose not to select a .ica file, it will just start an ungoogled-chromium browser session pointed at https://myvdi.dtcc.com where you can log in, download the .ica manually and chromium will be configured to automatically launch it with Citrix wfica on download completion.

The init script looks for ICA files in your XDG download dir (~/Downloads) and current working dir (i.e. the repo root). Again, this is not required if you just want a browser-based session within the VM instead.

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

Usage:

# Prompt for ICA file selection (can leave blank) and launch the VM.
