Fix #37: Add rapidjson-dev dependency and fix compilation issues

[chm10]

This pull request proposes a solution to address issue #37 and #34 by adding the missing rapidjson-dev package and fixing related compilation issues.

Proposed changes:

1. Add instruction to install rapidjson-dev package using apt-get
2. Update references to library packages to ensure correct dependencies
3. Fix several compilation warnings
4. Resolve compilation errors related to the missing package

To test these changes:

1. Install the rapidjson-dev package: sudo apt-get install rapidjson-dev
2. Rebuild the project
3. Verify that all compilation warnings and errors are resolved

These changes aim to improve the build process and potentially resolve the issues reported in #37.

I tested on /home/user/hailo-rpi5-examples folder need to be there.

After reinstalling

sudo apt-get install --reinstall hailo-tappas-core-3.28.2

Install the compiled package.

$ cd build.release/
$ sudo ninja install

After you can reboot run . setup_env.sh

Go back to the project folder.

$. setup_env.sh
Setting up the environment...

TAPPAS_POST_PROC_DIR set to /usr/lib/aarch64-linux-gnu/hailo/tappas//post-process/
Device Architecture is set to: HAILO8L

You need to be same folder like /home/user/hailo-rpi5-examples

$ python basic_pipelines/detection.py --help
usage: detection.py [-h] [--input INPUT] [--use-frame] [--show-fps] [--disable-sync] [--dump-dot] [--network {yolov6n,yolov8s,yolox_s_leaky}] [--hef-path HEF_PATH]
                    [--labels-json LABELS_JSON]

  -h, --help            show this help message and exit
  --input INPUT, -i INPUT
                        Input source. Can be a file, USB or RPi camera (CSI camera module). For RPi camera use '-i rpi' (Still in Beta). Defaults to /dev/video0

@chm10 Thanks alot for that PR (and others). I would add rapidjson-dev as a dependency of our installer for future releases. I don't get issues building this on the RPi did you installed hailo using the 'apt install hailo-all'? All dependencies should be resolved from the TAPPAS core package using: postprocess_dep = dependency('hailo-tappas-core', version : '>=3.28.2', required : false) or: postprocess_dep = dependency('hailo_tappas', version : '>=3.28.0')

Yes, I followed the documentation process, and have issue to install. I runapt install hailo-all following the step-by-step tutorial. The raspeberry 5 have compilation error to compile compile_postprocess.sh. As mentioned by anothers users.

Maybe the two files I modified need some review beucase have issue inside of them.
