Expose Progressive::timeOut() to Python

[thanhndv212]

Summary

continuousValidation::Progressive gained a configurable timeOut()
getter/setter in hpp-core (humanoid-path-planner/hpp-core#450), replacing
a hardcoded 15s wall-clock bound in validateStraightPath(). This binds
it so it's reachable from Python — without it, the new setting isn't
actually usable by any project that only talks to hpp-core through these
bindings (as opposed to linking hpp-core directly).

Depends on hpp-core#450 — needs that PR's Progressive::timeOut()
C++ method to exist before this can build.

Change

pathValidation::Progressive's pybind wrapper stores the concrete
validator behind a generic PathValidationPtr_t. Added a
ProgressiveWrapper with static getter/setter functions that downcast
to continuousValidation::ProgressivePtr_t via HPP_DYNAMIC_PTR_CAST,
matching the existing PVWrapper pattern already used for
validate()/validateConfiguration(). Bound as an overloaded timeOut
method (get with no args, set with a float arg) on the Progressive
Python class.

Testing

Built against a local hpp-core checkout with #450's changes applied;
verified from Python:

from pyhpp.core import Progressive
from pyhpp.pinocchio import Device
d = Device('test')
prog = Progressive(d, 0.001)
prog.timeOut()       # -> 15.0 (default, matches prior hardcoded value)
prog.timeOut(45.0)
prog.timeOut()       # -> 45.0
