Robbie Hammond 8e2760e83d Add fallback text for missing images (#397)
# What?
* When a prompt references an image path that doesn’t exist, replace it
with
  ```[missing image: <path>]``` instead of throwing an ENOENT.
* Adds a few unit tests for input-utils as there weren't any beforehand.

# Why?
Right now if you enter an invalid image path (e.g. it doesn't exist),
codex immediately crashes with a ENOENT error like so:
```
Error: ENOENT: no such file or directory, open 'test.png'
   ...
 {
  errno: -2,
  code: 'ENOENT',
  syscall: 'open',
  path: 'test.png'
}
```
This aborts the entire session. A soft fallback lets the rest of the
input continue.

# How?
Wraps the image encoding + inputItem content pushing in a try-catch. 

This is a minimal patch to avoid completely crashing — future work could
surface a warning to the user when this happens, or something to that
effect.
