Update camera.cpp

[saarors]

move
Replaced manual Vector3d initialization (v << vx, vy, vz;) with direct constructor:
const Vector3d v(vx, vy, vz);
Avoided repeated calls to pose_.translation() by storing it in a const reference:
const Vector3d& t = pose_.translation();
Used that reference to assign x_, y_, z_.

updatePose
Declared rotation matrix m as const and initialized it directly instead of default-construct + assign.
Replaced:
pose_ *= m;
with:
pose_.linear() = m;
(more explicit and avoids unnecessary transform multiplication)
Replaced manual vector construction:
Vector3d v;
v << x_, y_, z_;
pose_.translation() = v;
with:
pose_.translation() = Vector3d(x_, y_, z_);

setParameters
Added const to local helper variables.
Precomputed:
const float inv_width;
const float inv_height;
instead of dividing by width_ and height_ multiple times.
Minor formatting alignment for readability.
Changed z_nf to const.

Hello, you have to fix the formatting, according to clang-format. Also, give this PR a more meaningful title. Otherwise I would have to assume that this is just a spam pull request.
