Update / Remove @pythnetwork/pyth-sui-js depecrated warnings

[0xheartcode]

When using the aftermath-ts-sdk@1.3.14, we get the following warnings because of the deprecated pythonetwork/price-service-client

npm warn deprecated @pythnetwork/price-service-client@1.9.0: This package is deprecated and is no longer maintained. Please use @pythnetwork/hermes-client instead.

because of this:

  └── aftermath-ts-sdk@1.3.14
      └── @pythnetwork/pyth-sui-js@1.2.5
          └── @pythnetwork/price-service-client@1.9.0 (DEPRECATED)

fix:

       38 -      "@pythnetwork/pyth-sui-js": "^1.2.3",

Edit: the code seems to not be used anymore so the package can be removed ?
