feat(intrinsic_camera_calibrator): save partial preferences for initialization_view and ros_topic_view

[paulsohn]

Description

This PR allows to save and load the last selected options (preferences) for initialization_view and ros_topic_view of the intrinsic camera calibrator.

The preferences are saved in $HOME/.config/tier4/intrinsic_camera_calibrator.conf similar to below:

[initialization_view]
board_type=Dot board
data_source=ROS topic
parameter_profile_path=/home/taeseungsohn/workspace/CalibrationTools/install/intrinsic_camera_calibrator/share/intrinsic_camera_calibrator/config/c2_intrinsics_calibrator.yaml

[ros_topic_view]
qos_durability=VOLATILE
qos_reliability=BEST_EFFORT

Note. As the interplay of #267 , the following behavior can be observed:

• if the user manually selects a board type and then loads a config file, then the board type does not change.
• however, if the user only has a board type preference set from the previous launch, and has not selected a board type after the most recent launch, then loading a config file changes the board type.
