Maven multi module support

[NassimBtk]

This pull request adds support for handling and uploading output files from sub-modules in the build process. It updates the logic to correctly identify and locate these files, ensuring that sub-module outputs are included in the artifact upload workflow. The most important changes are grouped below:

Sub-module Output Support:

• Added entries for sub-module outputs (dummy-sub-module-1.0.00.pom and dummy-sub-module-1.0.00.txt) to the build info files, including their checksums and metadata. [1] [2]
• Added the actual sub-module output files (dummy-sub-module-1.0.00.pom and dummy-sub-module-1.0.00.txt) to the repository for testing and upload purposes. [1] [2]

File Location and Upload Logic:

• Updated readBuildInfoFile in src/buildinfo.js to collect only the output file names, not their paths, to avoid incorrect path assumptions for sub-module files. [1] [2]
• Added a new searchFilePath function in src/search.js to locate files by name anywhere in the project directory structure, addressing the challenge of sub-module file locations.
• Modified the upload process in src/run.js to use searchFilePath for resolving the actual file path before uploading each artifact, ensuring sub-module files are found and uploaded correctly. [1] [2]
