initial bindings work to expose prove function for PresentationV1

[squirer]

Purpose

Update concordium base to the version with exposed prove function, add the bindings for this function too

Changes

Updated base library, addded bindings method to lib.rs so that it can be called from Java

Checklist

• My code follows the style of this project.
• The code compiles without warnings.
• I have performed a self-review of the changes.
• I have documented my code, in particular the intent of the
  hard-to-understand areas.
• (If necessary) I have updated the CHANGELOG.

As far as I know, there also must be a context hashing function for anchor verification

In the Typescript SDK bindings, the presentation creation method accepts the following structure:

#[wasm_bindgen(js_name = createPresentationV1)]
pub fn create_presentation_v1(raw_input: JsonString) -> JsResult {
    let PresentationV1Input {
        request,
        global,
        inputs,
    } = serde_json::from_str(&raw_input)?;
    let inputs = inputs.iter().map(|i| i.borrow());
    let presentation = request
        .prove(&global, inputs.into_iter())
        .map_err(to_js_error)?;

    serde_json::to_string(&presentation)
        .context("Failed to serialize PresentationV1")
        .map_err(to_js_error)
}

It is PresentationV1Input, not PresentationV1ProofInput

Can you please use PresentationV1Input in Java and Swift bindings as well so we have the same models in our SDKs and have less confusion?

The structure is

struct PresentationV1Input {
    request: base::web3id::v1::RequestV1<ArCurve, Web3IdAttribute>,
    global: GlobalContext<ArCurve>,
    inputs: Vec<
        base::web3id::v1::OwnedCredentialProofPrivateInputs<IpPairing, ArCurve, Web3IdAttribute>,
    >,
}
