Cosmological likelihood evaluation for time-delay cosmography (TDC).

• Likelihood evaluation: TDCLikelihood() and TDCKinLikelihood() in tdc_sampler.py

• Running MCMC inference: fast_TDC() in tdc_sampler.py

• See test cases in tests/tdc_sampler_tests.py

This code was developed for the analysis in Erickson et al. (in DESC IR).
