Repository: ordinals/ord (rust)

Issue:
`ord wallet inscribe` with multiple parents
ord allows inscriptions with multiple parents (#2494) but not by it's own command.

```
$ ord wallet inscribe ... --parent X --parent Y
error: the argument '--parent <PARENT>' cannot be used multiple times
```

Pull request:
Add multi parent support to wallet
Closes #3586 and #2494
