1.5x the estimated gas when sending a message

[tkporter]

Seems like Goerli gas estimation has been a bit weird.

Estimating gas against the ankr public url (this is what the SDK uses):

$ cast estimate --rpc-url https://rpc.ankr.com/eth_goerli 0xDDcFEcF17586D08A5740B7D91735fcCE3dfe3eeD 'dispatch(uint32,bytes32,bytes)' 80001 0x000000000000000000000000bc3cfeca7df5a45d61bc60e7898e63670e1654ae 0x4d595f4d657373616765
34470

With a different public url:

$ cast estimate --rpc-url https://eth-goerli.public.blastapi.io 0xDDcFEcF17586D08A5740B7D91735fcCE3dfe3eeD 'dispatch(uint32,bytes32,bytes)' 80001 0x000000000000000000000000bc3cfeca7df5a45d61bc60e7898e63670e1654ae 0x4d595f4d657373616765
47666

Against anvil -f https://rpc.ankr.com/eth_goerli:

$ cast estimate --rpc-url http://localhost:8545 0xDDcFEcF17586D08A5740B7D91735fcCE3dfe3eeD 'dispatch(uint32,bytes32,bytes)' 80001 0x000000000000000000000000bc3cfeca7df5a45d61bc60e7898e63670e1654ae 0x4d595f4d657373616765
49428

Actual gas used against the anvil fork: 47432

So for now, just going to overestimate gas
