fix: Convert protobuf Point to python Vector.

[prmukherj]

Earlier solver.fields.reduction. was returning a protobuf message. Currently they are wrapped as a python class.

For instance:

Earlier behavior:

>>> x = solver.fields.reduction.force(locations=["wall"])
>>> x
x: 2.862068334485282
y: -2.5299803741481259
z: -0.0014375438414745349

>>> type(x)
<class 'ansys.api.fluent.v0.common_api_pb2.Point'>

Current behavior:

>>> x = s.fields.reduction.force(locations=["wall"])
>>> x                                                
(2.600005424922768e-31, -1.080374020897745e-24, 3.302743550728087e-17)
>>> type(x) 
<class 'tuple'>
>>> type(x[0]) 
<class 'float'>
