* allow trusted node sync based on LC trusted block root Extends `trustedNodeSync` with a new `--trusted-block-root` option that allows initializing a light client. No `--state-id` must be provided. The beacon node will then use this light client to obtain the latest finalized state from the remote server in a trust-minimized fashion. Note that the provided `--trusted-block-root` should be somewhat recent, and that security precautions such as comparing the state root against block explorers is still recommended. * fix * workaround for `valueOr` limitations * reduce magic numbers * digest len > context len for readability * move `cstring` conversion to caller * avoid abbreviations * `return` codestyle
