Discrete data capture routine

[pv33]

Create routine to capture data upon keypresses. Save imagery to file with incrementing file counter.
Use with #42

• Keypress/Enter Key based. color image only.
• Keypress/Enter Key based. color + puzzle mask for easier post-processing.
• Keypress/Enter Key based. color + depth saved (to file or to topic??).
• Glove based with state machine to trigger capture. Build out from detector.
• Possibly just hand based via depth image. Anything above valid workspace is a "hand"

Hand in scene: change state. Hand leaves: trigger capture. change state.

keypress method is easy for RGB only capture.
argument is prefix.
run capture loop for realsense.
run as loop until q is pressed or something to that effect.
capture triggered by Enter or C or D (for color/depth) or B (for both??)
maybe even capture image plus binary mask of puzzle pieces so that can be used after the fact. (enter P for puzzle mask? then saves image plus binary mask; run more code though.)

run glove detector.
configure a glove present/gone state.

Started in on a package mary_perception for including these things. Need to work out the details ... baby steps.
