It doesn't work with latest substrate due to a new type MultiAddress.

Hi,

I just followed recent commit from substrate, found that subxt couldn't work with latest substrate, error log like this:

Error: Rpc(Request(Error { code: ServerError(1002), message: "Verification Error: Execution failed: ApiError(\"Could not convert parameter `tx` between node and runtime: No such variant in enum MultiAddress\")", data: Some(String("RuntimeApi(\"Execution failed: ApiError(\\\"Could not convert parameter `tx` between node and runtime: No such variant in enum MultiAddress\\\")\")")) }))

And I noticed that the address type has been changed from

pub type Address = <Indices as StaticLookup>::Source;

to

pub type Address = sp_runtime::MultiAddress<AccountId, AccountIndex>;

Yes this currently only supports substrate 2.0.0 which is somewhat old now. I will update it this week hopefully - also will accept PRs.

Now the master branch supports it.
