a75903efe5 Add github actions 
This will build micropython's master branch with ulab support, and
then run the tests in tests/

At this time, there's only one test and it's not very useful.

fc80a25685 Increase CircuitPython compatibility 
- Adapt to signature of mp_make_new_fun_t for mpy and cpy by ifdef
 - Use MP_OBJ_IS_TYPE instead of mp_obj_is_type
 - Ditto MP_OBJ_IS_INT
 - Use mp_const_none instead of MP_ROM_NONE
 - Ditto mp_const_true, mp_const_false

f47abf90ac filter_convolve: fix build error 
My earlier change introduced a build error.  I'm not sure why
I didn't find this before making the pull request.

convolve: Optimize and special-case floats

7846b0c469 convolve: Optimize and special-case floats 
Special casing floats decreases runtime to about 50% (applying a 117-tap
filter to 512 points of data goes from 70ms to 32ms)

The top_n/bot_n calculations already meant that the a/c indices were
never out of range.  This decreases runtime further to about 15% of
original (11ms)

Timings done on an Adafruit Clue (nrf52840 at 64MHz)

It does of course increase code size somewhat.
