Driver panics on unresolved dependency

[phated]

Aim

The noirc_driver has primarily been used in nargo_cli where we attach a panic handler to capture failures; however, we are starting to use noirc_driver in the LSP where we shouldn't be having panics happen.

One such panic is when a dependency cannot be resolved. This should instead return an error diagnostic.

Expected Behavior

The driver should not panic and should instead return an error diagnostic for unresolved dependencies.

Bug

Driver panics, not diagnostics returned.

To Reproduce

1. Set up the LSP
2. Save a file with a dep that doesn't exist
3. LSP will crash
