Add the new flag
--save-invalid-block-temp
to save invalid gossip and received blocks to a temporary folder. This will be useful for the Deneb hard fork happening in one day. The choice of a feature flag and a temporary folder was made for their simplicity and minimal manual intervention. If necessary, we can later switch to a regular flag and a user-specified folder.
