SpiralGroundCurve with tests.

[agalbachicar]

🎉 New feature

Part of #265

Summary

Provides a spiral based GroundCurve. This implementation uses the functions that maliput::math brings in that belong to the Cephes library. On top of that, it adds some customization that the libOpenDrive library incorporates as ad-hoc customizations.

The result is a tested GroundCurve implementation that explores different conditions of the input parameters such that multiple cases are evaluated shuffling input curvatures, initial pose and arc length of the spiral.

Due to numerical error, tolerances are yet to be constrained for the inverse and the brute force integral comparison.

Test it

Via unit tests.
