v1.20.rc6 (rc1 too) -- TimeoutError class went missing

[martijnthe]

Somehow the TimeoutError class is "not defined" any more, even though there's this in esp32/mpconfigport.h:

#define MICROPY_PY_BUILTINS_TIMEOUTERROR            (1)

>>> TimeoutError
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'TimeoutError' is not defined

Note the "official" rc1 release also has this issue.

Root cause of this: micropython/micropython#4428

@Xykon @iwahdan88 the guys of the micropython upstream don't want to accept the fix (they want to remove TimeoutError entirely) but AFAICT do some of the Pycom classes rely on this, so you'll need to fix it on your own fork I think.
