description: str.ljust() and str.rjust() not implemented
cause: MicroPython is highly optimized for memory usage. Easy workarounds available.
workaround: Instead of `s.ljust(10)` use `"%-10s" % s`, instead of `s.rjust(10)` use `"% 10s" % s`. Alternatively, `"{:<10}".format(s)` or `"{:>10}".format(s)`.
