Add ability to pass level with revert

[kylriley]

It'd be helpful in some cases to be able to pass a level by the contract throwing, e.g. a level that requires you to exceed the block gas limit

Hmm. Interesting.

Can you make a suggestion as to how this would be achieved, considering Ethernaut.sol's validateInstance function?

This sounds useful, but it would be great to motivate it with an actual level idea that would work like this.

I guess that the gerneral try / catch solution already works for this but yes this might be handy with a level idea, fell free to open a github discussion under the "level idea" category and raise that up there. Closing this for inactivity
