fix: fix roadmark conversion bug

This is for bug fix of roadmark conversion. Bug description:

1. when handling roadmarks for road with multisections, each section takes the whole s values along the road as input parameter, which should be only the s values inside each section.
2. when handling the end s value of each section in a road, it take the end s value of the road as input, which should be only the s value of each section.

To fix it:

1. modify the corresponded code.
2. create a test map and corresponding tests for the changes.
