Data recording on ODCL node

[rland93]

400bd60 has a few things that should be useful for testing

• it creates test folders automatically.
• the typical directory where test data is saved is configurable via a ROS parameter called, /odcl/odcldir
• by default (i.e. if unset) the test data is saved to ~/odcldata/
• when the node is run, it will create a folder in ~/odcldata/ with today's date. So each day of testing will have its own date, making test data easier to manage
• two folders are made, raw, and crop, where images are stored
• a CSV file of each "run" of the odcl pipeline is also created. following An's idea each run has a prefix (01, 02...)

The raw image is saved with a unique identifier in /raw/
The cropped image of each target is saved with a unique identifier in /crop/

9e9360f has a few additions

Each found target is given a unique identifier, which is the date, run, frame, target.

• along with the 5 odcl parameters (lat lon scolor lcolor shape) we also have several new parameters and metadata
  • run number, frame number, target number, and target ID
  • time taken to inference
  • class confidence score

Whenever an image is captured as part of the pipeline, the exact capture time is recorded and saved

Right now, this code is UNTESTED. I plan to test tomorrow.
