Can't evaluate bytes pod-to-pod if using hubble control plane

**Describe the bug**
In the standard control plane, you can get pod-to-pod bytes data in the metrics using the packetparser plugin. It doesn't seem like if you use the hubble control plane there's any more granular than node-to-node bytes data (https://retina.sh/docs/Metrics/hubble_metrics/#node-level-metrics, forward_bytes).

Is there a good way in hubble CP with retina to be able to evaluate how much volume is moving between two pods?

**To Reproduce**
Steps to reproduce the behavior:

Install hubble CP and try and evaluate how much traffic is moving between two pods.

**Expected behavior**

Since standard CP is deprecated, offer a way using Hubble CP to get pod-to-pod bytes transmission data

**Screenshots**
If applicable, add screenshots to help explain your problem.

**Platform (please complete the following information):**

- OS: [e.g. AzureLinux] EKS
- Kubernetes Version: [e.g. 1.22] 1.33
- Host: [e.g. AKS, KIND, self-host, etc] AWS
- Retina Version: v0.0.36

**Additional context**

I can't move from standard CP if this functionality is not able to be replicated in the Hubble CP
