feat/606-enable-nat-traversal-via-hole-punching (#668)

Browse Source 
* feat: base implementation of dcutr for hole-punching

* chore: removed circuit-relay imports from __init__

* feat: implemented dcutr protocol

* added test suite with mock setup

* Fix pre-commit hook issues in DCUtR implementation

* usages of CONNECT_TYPE and SYNC_TYPE have been replaced with HolePunch.Type.CONNECT and HolePunch.Type.SYNC

* added unit tests for dcutr and nat module and

* added multiaddr.get_peer_id() with proper DNS address handling and fixed method signature inconsistencies

* added assertions to verify DCUtR hole punch result in integration test
