The most significant change in this release is how we create and sign extrinsics, and how we manage the
"additional" and "extra" data that is attached to them. See #477, and the
associated PR #490 for a more detailed look at the code changes.

If you're targeting a node with compatible additional and extra transaction data to Substrate or Polkadot, the main
change you'll have to make is to import and use subxt::PolkadotExtrinsicParams or subxt::SubstrateExtrinsicParams
instead of subxt::DefaultExtra (depending on what node you're compatible with), and then use sign_and_submit_default
instead of sign_and_submit when making a call. Now, sign_and_submit accepts a second argument which allows these
parameters (such as mortality and tip payment) to be customized. See examples/balance_transfer_with_params.rs for a
small usage example.

If you're targeting a node which involves custom additional and extra transaction data, you'll need to implement the
trait subxt::extrinsic::ExtrinsicParams, which determines the parameters that can be provided to sign_and_submit, as
well as how to encode these into the "additional" and "extra" data needed for a transaction. Have a look at
subxt/src/extrinsic/params.rs for the trait definition and Substrate/Polkadot implementations. The aim with this change
is to make it easier to customise this for your own chains, and provide a simple way to provide values at runtime.
