`les_protocol.nim` failed to build, due to very silly Nim bugs
nim-lang/Nim#8792 and nim-lang/Nim#17102.
import
../../[rlp, keys], ../../common/eth_types,
../[rlpx, kademlia, blockchain_utils], ../private/p2p_types,
The silly part is `../` has to be quoted if it's before a group of files, but
not before a single file. Most places in PR #344 / 7624153 use the workaround
`".."/` but it was missed in `les_protocol.nim`:
nimbus-eth1/vendor/nim-eth/eth/p2p/rlpx_protocols/les_protocol.nim(14, 3)
Error: cannot open file: ../../[rlp,keys]
