rpyodide 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.
