feat: subxt script to fund dev accounts via XCM

#47

Nicely done! One thing to add is three queries to Pop Network to ensure that alice, bob and charlie have received the funds.

Just thinking about this a little, would it not make sense to add this as a command to the pop-node binary? e.g. pop-node init.

It then becomes a first-class citizen, usable whenever a network launched, rather than compiling another side-car executable and manually launching. It could remain as its own crate, e.g. pop-node-init and be wrapped in a default feature so that it can be compiled out for releases if necessary.

I'm just thinking about the UX via pop-cli, where currently the node is automatically sourced and built. A node would be launched, but would not have any funds and users would not be able to deploy any contracts.

Also - have the .scale files been optimised to only include metadata for the pallets which are actually used? They seem large and I am sure that there is an option to trim them done to only the functionality which is used.

Unfortunately, it seems subxt has a bug with trimming metadata files (or I'm doing something wrong). Please see issue: paritytech/subxt#1509

Love the idea. This will be done in a separate PR as time allows. See tracker #57

Seems the pop interface is missing?

Everything works! Got an error messageQueue.ProcessingFailed but I think that was due xcmPallet.VersionNotifyRequested. The accounts were funded and the local network is set up as it should. One nitpick is the output:

It would be nice to make this look plain and simple so that the developer can simply read what happened and doesn't get confused. E.g.:

XCM Reserved Transfer sent from relay.
Checking Pop Balances:
Alice: amount
Bob: amount
Charlie: amount

Another thing is documentation. We should explain simple and short what is happening when someone spins up a local network with Pop Network.

Both docs & output can be done in issue #57 as well

LGTM. Looking forward to seeing it as a pop-node command!

Interesting that the output includes Rococo, which should not be the case?
