Why does this crate exist?

I originally created the TFVPKTool TypeScript library to support reading Respawn VPK files, along with Harmony VPK Tool using Electron.

I very quickly noticed the issue that these often resulted in high memory use due to language and ecosystem I had used.

With sourcepak I am aiming to fix that.
