Adding CI testing

Triggered at:

    For pushing changes to master or dev branches
    For pull requests to master or dev branches

Features:

    Uses Julia 1.9.3 (we can change or increase number of versions to be tested and supported later)
    Uses ubuntu-latest in x86 architecture
    Uses DVC to pull sample files (login to cybele using guptaa account)
    Runs test using julia's native test feature.
    CodeCov needs to be setup for reporting code coverage of the tests.
