[Python] enumerate built-in function is not defined

[bisam69]

The 'enumerate' function which is part of Python since version 2.3 and also part of Micropython 1.9.3 as shown here seems to have been forgotten on calc.

Looks like it's this config line (there are interesting things around it as well), to set to 1:

epsilon/python/port/mpconfigport.h

Line 37 in 21b5e89

#define MICROPY_PY_BUILTINS_ENUMERATE (0)

That's a good catch. Thanks @bisam69 !

@Ecco after #521 can this be done?

It's all good 😄
