Clarify that measureInputUsage takes more than just a string. #126
Description
The explainer shows several examples measureInputUsage(promptString), but it might be worth noting that it can also measure multimodal content.
session.measureInputUsage([{
role: "user",
content: [
{ type: "audio", value: audioBlob }
]
}])
Even just changing promptString to promptMessages might make it more obvious that measureInputUsage works for more than just string prompts without looking at the IDL.
