Fix for timePrecison

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used [patch-package](https://github.com/ds300/patch-package) to patch `react-native-maps-directions@1.8.0` for the project I'm working on.

Here is the diff that solved my problem:

This issue body was [partially generated by patch-package](https://github.com/ds300/patch-package/issues/296).

Review index.d.ts and src/MapViewDirections.js, starting with the supplied diff and the existing timePrecision declaration and Polyline rendering. Confirm that the prop uses the correct type name and that the directions component renders through the imported Polyline, then verify the package still builds and behaves as expected.
