[WIP] Soroban XDR

[paulbellamy]

Work-in-progress branch using the soroban XDR. Pretty rough-and-ready, but you can build InvokeHostFunctionOperations

You can do:

let invokeHostFunctionOp = new StellarBase.Contract("add_u32_contract_id").call(
  "add",
  xdr.ScVal.u32(5),
  xdr.ScVal.u32(8)
);
// Then use it as a normal Operation.

TODO

• [ ] figure out signing for invokeHostFunction operations
• [ ] nicer contractSpec based method wrapper
• [ ] Enforce some of the intricacies around how invokeHostFunctions can be used. e.g. must be the only function in the transaction
• [ ] Nicer scval input based on strval in soroban-cli

@paulbellamy Apologies, I accidentally published a new version of this branch while trying to debug an issue in Freighter. It just created a new version 8.2.2-soroban.8 that is exactly the same as soroban.7. NPM won't allow that version to be unpublished and reused, so the next version will need to be 8.2.2-soroban.9.

Again, sorry about that. The automated pipeline worked a bit too well, it seems 😬
