Unable to register assets by name in New Runtime, only unique name

Description

When registering out of bound assets, in the Legacy Runtime, we had more granular access to and could match against the name() of the asset.

For example, say I'm using Roboto as a custom font, I could then do the following:

let viewModel = RiveViewModel(fileName: "my_rive_file") { asset, _, factory in
      if let fontAsset = asset as? RiveFontAsset {
          guard fontAsset.name() == "Roboto" else { return false }
          let decodedFont = factory.decodeFont(Data(...))
          fontAsset.font(decodedFont)
          return true
      } else {
          return false
      }
  }

In the New Runtime, we no longer have the same level of access to the underlying asset. So the above now translates into the following, where ideally I continue to register my asset by name:

let worker = try await WorkerProvider.shared.worker()

let font = try await worker.decodeFont(from: Data(...))
worker.addGlobalFontAsset(font, name: "Roboto")

This actually doesn't work, because, internally, Rive is now looking up and matching assets against uniqueName(), not name().

/rive-ios/submodules/rive-runtime/src/command_server.cpp
  Line 64: auto itr = m_fontAssets.find(asset.uniqueName());
           // Looks up "WeGoSansVariable-1234567" — NOT "Roboto

asset.uniqueName() is implemented as:

/rive-ios/submodules/rive-runtime/src/assets/
  Line 27: std::string FileAsset::uniqueName() const
  Line 30:     std::string uniqueName = name();          // "Roboto"
  Line 37:     return uniqueName + "-" + std::to_string(assetId());  // "Roboto-1234567"

For out-of-bound assets like Fonts, ideally we can continue to match against the Font name(), rather than needing to know what the uniqueName() will be, as we can only currently get that when exporting the .riv file.
