rblimp 1.1.0

• Added an as.array() method for blimp_obj that returns an
  [iterations, chains, parameters] 3-D array compatible with bayesplot.
  Supports a warmup = c("exclude", "include", "only") argument for
  including burn-in draws; when warmup = "include" the returned array
  carries an "n_warmup" attribute so it pipes directly into
  bayesplot::mcmc_trace(arr, n_warmup = attr(arr, "n_warmup")).
• Added S3 methods registering blimp_obj with the posterior package's
  as_draws(), as_draws_array(), and as_draws_df() generics, unlocking
  the posterior / bayesplot summary and plotting ecosystems. posterior
  is a soft dependency (in Suggests).
• Trace plots now display rank-normalized split-Rhat (Vehtari et al., 2021)
  instead of the basic PSRF, and fixed facet labels when plotting a subset
  of parameters.
