Changes in version 0.1.0                        

  - Initial version: call Python (Pyodide) from R in webR, with a
    reticulate-style API.
  - py_run_string(), py_run_file(), py_eval(), import(), py, r_to_py(),
    py_to_r(), tuple(), dict(), and $, [[, [ on Python objects.
  - Conversions for vectors, lists, matrices and arrays (NumPy), data
    frames (pandas), POSIXct and difftime, and pandas Series (named by
    their index).
  - py_require() declares Python requirements, like
    reticulate::py_require(), including deps = FALSE for packages whose
    pins can't be met in Pyodide. py_install() installs packages with
    micropip.
  - Several independent Python sessions: pyodide_start(), use_pyodide(),
    pyodide_stop(), pyodide_sessions().
  - Files whose paths are passed to Python are copied from webR's file
    system to Pyodide's; py_upload() copies other files.
  - cpython_start() runs the same Python bridge in a local CPython
    process, so rpyodide (and code using it) can be tested outside webR,
    including on CRAN.
