Function getEC2Instances

getEC2Instances(
instanceTypes: EC2InstanceType[],
): Map<EC2InstanceType, EC2InstanceDetails>
Get multiple EC2 instances at once. More efficient than calling getEC2InstanceInfo multiple times for batch operations.
Parameters
- instanceTypes: EC2InstanceType[]
  Array of instance types to fetch
Returns Map<EC2InstanceType, EC2InstanceDetails>
Map of instance type to details
Example
```
import { getEC2Instances } from 'aws-instance-info'

const instances = getEC2Instances(['m5.large', 'm5.xlarge', 'c7.2xlarge'])

for (const [type, details] of instances) {
  console.log(`${type}: ${details.vCPUs} vCPUs`)
}
// m5.large: 2 vCPUs
// m5.xlarge: 4 vCPUs
// c7.2xlarge: 8 vCPUs
```
