This is a minimal set of changes to make things work with the new types
in nim-eth - this is the minimal PR that merely resolves
incompatibilities while the full change set would include more cleanup
and migration.
* Add nph check to nimbus_verified_proxy CI lint
* Formatting nimbus_verified_proxy code with nph v0.4.1
* Update copyright years
* Change order of nph check vs copyright check
* Reduce Nim 1.6 compiler warnings/hints for Fluffy and Nimbus proxy

unnecessary imports.
