(draft)deps(experimental): uniffi 0.30.0

[reez]

Description

Testing uniffi 0.30.0

Two changes:

1. export Ord trait so swift and kotlin now treat them as comparable value types
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 9fa0fa0f7de34378623e24284cae85e6c77a5946 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.
