getElastiCacheNodeInfo(nodeType: string): Promise<ElastiCacheNodeDetails>
Get detailed information for a specific ElastiCache node type. Triggers the initial bulk fetch on first call; subsequent calls use LRU cache.
Parameters
- nodeType: string
  The node type (e.g., "cache.m5.large")
Returns Promise<ElastiCacheNodeDetails>
Promise resolving to node type details including vCPUs, memory, and network specs
Example
```
import { getElastiCacheNodeInfo } from 'aws-instance-info/async'

const node = await getElastiCacheNodeInfo('cache.m5.large')
console.log(node.nodeType) // 'cache.m5.large'
console.log(node.vCPUs) // 2
console.log(node.memoryGiB) // 6.38
console.log(node.networkPerformance) // 'Up to 10 Gigabit'
```
