Support enode-id

[AgeManning]

Upgrade to the latest ENR and also print an enode-id.

This leaves the TCP field blank if one does not exist in the ENR.

If an IP address does not exist, this does not print any ports.

I confirm that it works:

$ target/debug/enr-cli read "enr:-Je4QEeZoiY8OrUxlckLuU8leuuSfnrveD8PdUnCvHavJJzcGQn7nKikWNV_ZxbRtPt6si-tQNwT_aIYpksq3O2Hzblbg2V0aMfGhPCv0OOAgmlkgnY0gmlwhIe10fKJc2VjcDI1NmsxoQNGM7sxj2Wuen_j9kqzHEmjqSxct1UxxbA9kwl7ha7NRIN0Y3CCdl-DdWRwgnZf"
ENR Read:

Thanks a lot!

For the record, answered my question on https://ethereum.stackexchange.com/questions/137275/how-to-translate-an-ethereum-enr-address-to-an-enode-address/138063#138063

Thanks again!

@monperrus - There was a bug in the previous implementation. The formatting for the enodeid was wrong. I have corrected it.

Also, couldn't find an exact specification, but the overview here: https://ethereum.org/en/developers/docs/networking-layer/network-addresses/#enode

Suggests that if the discovery port and the tcp port are the same, then to only list a single port.

I've made these changes.

great thanks!
