Function getRouteProgressForSection

getRouteProgressForSection(
route: Route,
section: SectionProps,
): RouteSegmentProgress | undefined
Calculates progress measurements for a route section.

Convenience wrapper around getRouteProgressBetween that accepts a SectionProps directly, using its startPointIndex and endPointIndex as the segment bounds.
Parameters
- route: Route
  The route whose properties.progress will be used for interpolation.
- section: SectionProps
  The section whose start and end point indices define the segment.
Returns RouteSegmentProgress | undefined
A RouteSegmentProgress object, or undefined when either index cannot be interpolated (see calculateProgressAtRoutePoint for the full list of conditions).
Example
```
const section = route.properties.sections.countries[0];
const result = getRouteProgressForSection(route, section);
if (result) {
  console.log(`Section starts ${result.start.distanceInMeters} m from route origin`);
  console.log(`Section ends   ${result.end.distanceInMeters} m from route origin`);
  console.log(`Section length ${result.delta.distanceInMeters} m`);
  console.log(`Section takes  ${result.delta.travelTimeInSeconds} s`);
}
```
