Please describe the feature you’d like to see added.
Currently submitpackage does no sanity checks on submitted transactions.
These checks have been helpful more than a handful of times in the wild, and these arguments are actively used by downstream wallets. We should figure out how to support them

Describe the solution you’d like
maxfeerate: this one is a bit tricky. I think the easiest way would be have a utility function that pulls in utxos to create the sigops-adjusted vsizes and individual fees? Then the entire package could be rejected if any exceed the set amount.
maxburnamount: This can be added on without any chain-context by scanning the outputs of each transaction and rejecting the package if any exceed the value.
