Delio Brignoli f98bb2ddcb py/mpprint: Fail an assertion with unsupported format specifiers.
Arguments of an unknown type cannot be skipped and continuing to parse a
format string after encountering an unknown format specifier leads to
undefined behaviour.  This patch helps to find use of unsupported formats.
