Luan Taraschi b9f591b665 Follow CPython's padding rules in a2b_base64 (#8570 )

With strict_mode=True the decoder accepted padding CPython rejects:

    >>> binascii.a2b_base64(b'YWJj=', strict_mode=True)
    b'abc'

It also dropped data in the default mode, because it returned at the
first pad that completed a quad:

    >>> binascii.a2b_base64(b'abc=a')
    b'i\xb7'          # CPython: b'i\xb7\x1a'

The loop now counts pads and decides at the end, the way CPython does,
so a stray pad is ignored outside strict mode and named as leading,
excess or discontinuous inside it. DecodeError::InvalidPadding was dead
in this file and now carries the excess padding message.

test_base64_strict_mode and test_base64_excess_data were marked as
expected failures and pass now.

README.md

Standard Library for RustPython

This directory contains all of the Python files that make up the standard library for RustPython.

Most of these files are copied over from the CPython repository (the 3.7 branch), with slight modifications to allow them to work under RustPython. The current goal is to complete the standard library with as few modifications as possible. Current modifications are just temporary workarounds for bugs/missing feature within the RustPython implementation.

The first big module we are targeting is unittest, so we can leverage the CPython test suite.
