Function calculateSourceSampleTimestamps

calculateSourceSampleTimestamps(
    firstSampleUnixNs: bigint,
    sampleIntervalNs: bigint,
    valueCount: number,
): number[]
Calculates the time of every value in a scan batch.

The time of values[i] is firstSampleUnixNs + i * sampleIntervalNs, computed in bigint and then converted to milliseconds.
Parameters
- firstSampleUnixNs: bigint
  Time of values[0], Unix epoch, in nanoseconds.
- sampleIntervalNs: bigint
  Time between consecutive values, in nanoseconds.
- valueCount: number
  Number of values in the batch.
Returns number[]
Unix epoch times in milliseconds (with fractions), one per value, or an empty array if valueCount is not a positive finite number.
Example
```
const times = calculateSourceSampleTimestamps(
  scan.firstSampleUnixNs, scan.sampleIntervalNs, scan.values.length);
```
