Proposed Changes

This change will log the value of the relay block and the local block when the relay block is more profitable.

Additional Info

This change will help validators understand the block selection (as it looks like the execution reward sometimes is higher that the MEV-reward).

The rationale for this change is to aid operators to better understand why a relay-block was chosen over a local block.
Looking at produced blocks (at beaconcha.in for example) it sometimes looks like the builder is making a profit just from the execution reward vs the MEV-reward, and creates the nagging question: "Could i have built this block and made that extra profit?"... The answer is probably "No, not without the extra transactions included by the relay", but by logging the value of the local block-candidate, this will no longer be an issue..

I am not getting the same errors when running "make cargo-fmt"?

@p4fg Is your Rust compiler up to date? What does rustc --version show?

Even if it is outdated, it's strange that it wouldn't pick up the error. Rustfmt has always preferred K&R style braces to Allman/BSD style.

@michaelsproul : I fixed the cargo-fmt bug, will it be automatically retried or do i have to do something?
