Nargo crashes when adding a method to an unsupported type

[signorecello]

Aim

I was trying to write code and made something illegal:

type BN = BigNum<3, 254, BN254_Fq_Params>;
impl OneZero for BN {
.... etc

Expected Behavior

Expected the LSP to tell me about the error. I can see it in the console:

Message:  �[36minternal error: entered unreachable code: Cannot add a method to the unsupported type 'BN'�[0m
Location: �[35mcompiler/noirc_frontend/src/node_interner.rs�[0m:�[35m1411�[0m

This is a bug. We may have already fixed this in newer versions of Nargo so try searching for similar issues at https://github.com/noir-lang/noir/issues/.

Bug

It shouldn't crash because of the error, simply tell me and keep going.

To Reproduce

1. Try the above code
2. See the LSP crash
