feat!(types): Add Blob::index field introduced in celestia 0.13

[S1nus]

Another attempt at adding this field. Now, trying to use an Option<u64>.

Looks good 👍 left some suggestions

[zvolin]

could you look into the CI failures too?

[zvolin]

some of the failures seems to be coming from toolchain updates, I'll look into that tomorrow

[zvolin]

I have a fix for clippy and docs failures in #275. Unfortunately the rest of Lumina team is off-site, so if I won't find any reviewer, this will have to wait till Thursday.

I think those test failures are related to this change tho https://github.com/eigerco/lumina/actions/runs/8976014314/job/24653654722?pr=274

@S1nus I've just noticed that the commits aren't signed
Would you mind setting up commit signing and force-pushing? Checks won't allow merge unless all commits are signed.

[zvolin]

Hey @S1nus, I took closer look on why do the tests fail. Hope you didn't mind my interference 🙏

So it turned out that the index field is always set when making requests using celestia blob submit ... cli. Example request caught using mitmproxy looks like:

{
    "id": 1,
    "jsonrpc": "2.0",
    "meta": {
        "SpanContext": "AABS1z6HOiQ+SS/vuHkNa2YrARBcp1onueEeAgA="
    },
    "method": "blob.Submit",
    "params": [
        [
            {
                "commitment": "27wECh7o43HkyXIRS0kcVMoJD9iWVNIEARmP4AlsjeM=",
                "data": "IkhlbGxvIHdvcmxkIg==",
                "index": -1,
                "namespace": "AAAAAAAAAAAAAAAAAAAAAAAAAAAADCBNOWAP3dM=",
                "share_version": 0
            }
        ],
        -1
    ]
}

this also makes sure that binary serializers will always serialize / deserialize the same type, this isn't issue in case of jsons, but could be for other like bincode or risc0

@fl0rek I set up signing, newer commits are signed. is it good? or need to do something else?

[zvolin]

Previous commits needed to be signed too, but I just squashed them and it looks fine. I've added the fix for celestia-rpc tests, hopefully CI will be happy now
