rABCd9be9a3dbe35: [chronik] Electrum: add the blockchain.headers.subscribe endpoint

Summary

Subscribe to get the new header when a block is connected.

This requires karyon version 0.2.2 so we can inject our own custom notification encoding function.
The format has been fixed since D18068.

Test Plan

./test/functional/test_runner.py chronik_electrum_*

In terminal 1:

./src/bitcoind -regtest -debug=chronik -chronik -chronikscripthashindex -chronikelectrumbind="127.0.0.1:50001"

In terminal 2 (can be done in several terminals):

echo '{"jsonrpc": "2.0", "method": "blockchain.headers.subscribe", "params": [], "id": "test"}' | nc 127.0.0.1 50001 | jq

in terminal 3:

./src/bitcoin-cli -regtest createwallet regtest
./src/bitcoin-cli -regtest -generate 1
