Elaborate on deploying TimeGPT to own infra / clarify terms

[daveqs]

https://github.com/Nixtla/nixtla/blob/main/README.md mentions deploying TimeGPT on user's own infrastructure in two places:

1. "Alternatively, deploy TimeGPT on your own infrastructure to maintain full control over your data and workflows."

2. "As the only foundation model for time series analysis out of the box, TimeGPT can be integrated via our public APIs, through Azure Studio (coming soon), or deployed on your own infrastructure."

However, this repo contains only the SDK, not the model implementation to be self-hosted. Also, the readme indicates that TimeGPT itself is closed-source, while the the Apache 2.0 license applies to the SDK.

Please provide access to TimeGPT for self-hosting if that is your intent, or provide a link to where it made available, and clarify the terms under which it can be self-hosted.

Many thanks!
