The old CI script was building bayeswave against a LIGO software environment that is no longer updated. This merge:
Creates a dependency image every night using the latest released versions of LIGO software (e.g., LALSuite). Ensures correct operation in LDG environments.
Introduces nightly build and operation tests
Tests the build and operation of every commit to bayeswave in that environment
Builds and deploys a nightly docker image of BayesWave
Tests the build of the BayesWave RPM
Installs BayesWave into its container via the RPM built in CI
