deps: uniffi 0.30.0

Description

Testing uniffi 0.30.0

Two changes:
0. bumping to 0.30.0

1. export Ord trait so swift and kotlin now treat them as comparable value types

Notes to the reviewers

Tested out this other thing along the way but didn't work
2. (breaking! but potentially awesome) convert HashableOutPoint from an object to a record "Enums and Records can have methods" compiles but exporting our own methods on a record fails in bindgen step

@thunderbiscuit + @ItoroD this is just a draft/experiment on 2 new things in uniffi 0.30.0

[thunderbiscuit]

We can probably do this bump to 0.30.0 now that 2.2.0 is released. It just needs a rebase and a clear vision for the Ord + Hashable stuff.

We can then figure out if the new Display on the Errors is a breaking change (I don't actually think it is?), but that can come in a separate PR.

ok so 2 commits now, one just bumping to 0.30.0, and the other (which we can keep in this pr or spin out into another pr, whatever is cool w me) is relating to the ord+hashable stuff.

in that second commit 9fa0fa0 I'm applying it for BlockHash, Txid, Wtxid, DescriptorId, and TxMerkleNode

Before this BDK iOS app would have had to compare txids indirectly lhs.outpoint.txid.description < rhs.outpoint.txid.description or doing a manual Comparable extension, (id assume Kotilin is somewhat "comparable" to swift).

But after this change the generated Swift bindings now declare those types as Comparable, so i can sort UTXOs directly with lhs.outpoint.txid < rhs.outpoint.txid https://github.com/bitcoindevkit/BDKSwiftExampleWallet/pull/334/files#diff-53a4180956cd49d7d1972a362feac43ba63abe4268a7d5aa6d99456554c64662 (I used locally generated swift bindings form this branch to test) without the string/hex workaround which tidy's up the code.
