InnerTxnBuilder ABI arguments

[barnjamin]

Problem

It should be straightforward to construct a transaction or group of transactions that follow ABI spec.

At the moment all args must be manually passed with the correct encoding including remembering to set reference arguments correctly.

Solution

Something like

#...
(arg1 := abi.Uint64).set(Int(10)),
(arg2 := abi.Account).set(Txn.accounts[0]),
(arg3 := abi.String).set(Bytes("lol")),
InnerTxnBuilder.Begin(),
InnerTxnBuilder.MethodCall(app_id, method_def, [arg1, arg2, arg3]),
InnerTxnBuilder.Next(),
#...
