Support cacheCreationInputTokens in Usage Data

[firebuzz-dev]

Anthropic returns this metadata for token usage which includes cache creation token usage as well.

anthropic: { cacheCreationInputTokens: 46209, container: null, stopSequence: null, usage: { cache_creation: { ephemeral_1h_input_tokens: 0, ephemeral_5m_input_tokens: 46209, }, cache_creation_input_tokens: 46209, cache_read_input_tokens: 0, input_tokens: 337, output_tokens: 342, service_tier: "standard", }, },

But this data is not available in usageHandler.

Is it available in the raw request response handler metadata?

Yes, it is. We just need to put into usage handler to make it clean. It's a quick win.

creation token usage as well.

anthropic: { cacheCreationInputTokens: 46209, container: null,

stopSequence: null, usage: { cache_creation: { ephemeral_1h_input_tokens:

0, ephemeral_5m_input_tokens: 46209, }, cache_creation_input_tokens: 46209,

cache_read_input_tokens: 0, input_tokens: 337, output_tokens: 342,

service_tier: "standard", }, },

But this data is not available in usageHandler.
