Toppra

Added
- [python] seidelWrapper solves 1d LP instead of 2d LP when x_min == x_max and solve_1d > 0
- [python] Fixed planning_utils.py to follow the latest api of toppra.algorithm.ParameterizationAlgorithm
- [cpp] add initial gridpoints to proposeGridpoints method.

Changed
- fix: the f-string bug when hot_qpoases solver failed (208)
- feat(solver): Make seidel solver(cython) solves 1D LP when possible (223)
- feat(cpp,constraint): Make Interpolation the default method (225)
- fix(util): toppra.compute_trajectory() does not return aux data. (224)

- [cpp] always define all installed symbols.
