chore: bindings return multiaddress array

[Ivansete-status]

Description

Adding new function that helps to extract the multiaddresses the node is listening to. The information is returned as a string with that contains a JSON-array. e.g.: ["/ip4/100.79.7.227/tcp/60001/p2p/16Uiu2HAm2eqzqp6xn32fzgGi8K4BuF88W4Xy6yxsmDcW8h1gj6ie"]

kudos to @richard-ramos! It's been a great pair programming session :)

Changes

• examples/cbindings/waku_example.c: adapt signatures to accept the recently added void* userData (outside of the scope of this PR.)
• examples/cbindings/waku_example.c: invoke waku_listen_addresses(ctx, event_handler, userData);
• library/waku_thread/inter_thread_communication/requests/debug_node_request.nim: new file added.
• library/libwaku.nim, libwaku.h: waku_listen_addresses implementation

How to test it

1. make cwaku_example -j11
2. ./build/cwaku_example --host=0.0.0.0 --peers=/dns4/node-01.do-ams3.wakuv2.test.statusim.net/tcp/30303/p2p/16Uiu2HAmPLe7Mzm8TsYUubgCAW1aJoeFScxrLj8ppHFivPo97bUZ --port=60001 --key=364d111d729a6eb6d2e6113e163f017b5ef03a6f94c9b5b7bb1bb36fa5cb07a9
