Error: Cannot use circuit for type field in: ...

[jfecher]

Aim

When including the type field in the Nargo.toml, if an invalid value like "circuit" or "binary" are given, the compiler panics and issues an error message that explains the field is incorrect but does not give the possible valid values of the field.

Expected Behavior

The compiler should not panic and should suggest the possible valid values of the field

@phated can you take a look at this

[phated]

Will do! I want to find a better way for Nargo CLI errors to be written. Something like the error message and then a longer message that contains useful suggestions like this.
