[TASK] Expose fields getter for Note inner JsNote

[AhmedKorim]

Overview

The current Note class doesn't expose the inner JsNote fields, to reach those data the user has to access the inner type
The goal here is to expose the inner type fields

Spec

Fields to expose

Fields are defined in the inner type JsNote after building packages/wasm-utils/build/wasm-utils.d.ts

Getters

 get HashFunction () {
   return this.note.hashFunction ;
 }
 

for importing types from wasm-utils use import type {xxx} from '@webb-tools/wasm-utils
EX import type {HashFunction} from '@webb-tools/wasm-utils'

Tests

Similar to the tests we have in the note.spec.ts packages/sdk-core/src/__test__/note.spec.ts, Add a test that leverages those getters and insure that the values are correct
