nimiq-consensus panics via RequestMacroChain micro-block locator

Impact An unauthenticated p2p peer can cause the RequestMacroChain message handler task to panic by sending a RequestMacroChain message where the first locator hash that is on the victim’s main chain is a micro block hash not a macro block hash. In RequestMacroChain::handle, the handler selects t...
