Ogmios connections leak

[arjaz]

I think the reconnect during the network sync doesn't terminate the connections correctly.

With Xogmios trying to reconnect the number grows indefinitely.

As soon as I terminate the Xogmios application all open connections are dropped.

@arjaz Thanks for reporting the issue 🙏

Mind checking if the fix-reconnection-leak branch works for you ?

{:xogmios, github: "wowica/xogmios", branch: "fix-reconnection-leak"}

Then I can merge this PR and push an update to hex
