process.stdin stream for passing into new process.spawn equivalent (process.create?)

[Corecii]

Created from a Discord conversation

[1:49 PM] (Erica) DevComp: ill implement a process.stdin which hands you the stdin you were given [1:49 PM] (Erica) DevComp: and you can put that in SpawnOptions [1:50 PM] Shae (Corecii): that would work great, thank you for your work on this! [6:31 AM] (Erica) DevComp: can you create an issue on lune for this [6:31 AM] (Erica) DevComp: i want to get this done in this week and I might forget

This would allow for a simple way to pass the Lune process's stdin into a process created with the process API, allowing user input.
