D435if depth camera expanded fov and intrinsics

[hello-binit]

From PR #54:

• The depth cameras use the same intrinsics as the rgb cameras. For the D405 this is fine since it's a stereo RGB pair. The D35i depth camera has a wider FOV than the color camera, however, we don't have a correction for this in mujoco, so we're using the same FOV and Focal for now.
• The Navigation camera is missing calibrated Focal values.
