closes #580

[what-the-diff]

PR Summary

• Introduction of package.yml file for the gaia-gis.it/libspatialite project
  This file contains pertinent information about the software distribution, such as its version details and the other software it relies on (dependencies). This enhancement simplifies the management and sharing of the project.

• Inclusion of build instructions for the project
  The new instructions aid in smoothly setting up the project. Actions include patching (modifying) the configure file, running this file (it checks the system's ability to compile the software), and executing make and install commands (they compile the raw code into a format that your computer can understand and then place this compiled code in appropriate locations).

• Addition of a test script to confirm the installed version of spatialite
  This useful script automatically checks the installed version of spatialite using a utility known as pkg-config, ensuring that the version used is consistent and up-to-date. This adds an extra layer of reliability to the project.
