cmdstanr v0.5.3

• On Windows, users can now install and use CmdStan with WSL (Windows Subsystem for Linux). Set wsl=TRUE in install_cmdstan() to install CmdStan for use with WSL. This can offer significant speedups compared to native Windows execution. (#677, credit goes to @andrjohns)

• In cmdstan_default_path() we now ignore directories inside ~/.cmdstan that don't start with "cmdstan-". (#651)

• Fixed Windows issues related to not locating grep.exe. (#661, #663, credit goes to @weshinsley)

• Fixed a bug in diagnostic checks when ebfmi is NaN.

• Fixed a bug that caused issues when using ~ or . in paths supplied to the cmdstanr_write_stan_file_dir global option.

• Fixed a bug that caused the $time() method to fail when some of the chains failed to finish successfully.
