Bug fixes

• Fixed reading inverse mass matrix with values written in scientific format in
  the CSV. (#394)

• Fixed error caused by an empty data list. Previously if a model didn't require
  data then data had to either be NULL or be a non-empty list, but now list()
  is allowed. (#403)

New features

• Added $sample_mpi() for MCMC sampling with MPI. (#350)

• Added informative messages on compile errors caused by precompiled headers (PCH). (#384)

• Added the cmdstanr_verbose option for verbose mode. Intended for
  troubleshooting, debugging and development. See end of How does CmdStanR work?
  vignette for details. (#392)

• New $loo() method for CmdStanMCMC objects. Requires computing pointwise
  log-likelihood in Stan program. (#366)

• The fitted_params argument to the $generate_quantities() method now also
  accepts CmdStanVB, posterior::draws_array, and posterior::draws_matrix
  objects. (#390)

• The $optimize() method now supports all of CmdStan's tolerance-related
  arguments for (L)BFGS. (#398)

• The documentation for the R6 methods now uses @param, which allows package
  developers to import the CmdStanR documentation using roxygen2's
  @inheritParams. (#408)
