This commit introduces a new executable, spinner,
which supports two types of animations for boot sequences:
1 rotates square PNG images per frame
2 shows a sequence of square images from a strip of PNG images.
it supports read configuration from a conf file.
the default path of conf is /usr/share/platsch/spinner.conf
the dir of the conf can be set via env platsch_directory
here is an example of conf:
backdrop="/usr/share/platsch/splash.png"
symbol="/usr/share/platsch/Spinner.png"
fps=20
frames=0
text="Now loading..."
text_x=350
text_y=400
text_font="Sans"
textsize=30

+Spinner - Splash Screen with Animation
+======================================
+
+The `spinner` executable is designed to provide boot animations. It supports
two types of animations:
+
+1. **Square PNG Rotation Animation**: Rotates a square PNG image.
+2. **Sequence Move Rectangle Animation**: Displays a sequence of square images
from a strip of PNG images.
+
+spinner Configuration
+---------------------
+
+The configuration for the `spinner` executable is read from a configuration
file,
+with a default path of `/usr/share/platsch/spinner.conf`.
+The directory of the configuration file can be set via the `platsch_directory`
environment variable.
+
+Example Configuration File
+--------------------------
+
+Here is an example of a configuration file (`spinner.conf`):
