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

[acraigupgrade]

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

@acraigupgrade the data is in the summary section of the flows. it is in RetinaMetadata struct

retina/pkg/utils/flow_utils.go

Line 131 in 15cb059

func AddRetinaMetadata(f *flow.Flow, meta *RetinaMetadata) {

@vakalapa Is that available currently in the exposed metrics, though? I didn't see that. I'd like to have access to pod-to-pod bytes data in the metrics for further enrichment
