update MANIFEST.in to package only the main source

wnienhaus · wnienhaus · commit b2a13ae22a1d · 2021-11-24T22:02:00.000+02:00
The MANIFEST.in will exclude documentation, examples and tests
and all files in the repo root. This way only the main source
in esp32_ulp/ will be packaged by sdist.

Since we're packaging to upip format, which can only be installed
by MicroPython/upip, we leave out all files that are not strictly
needed to run on the ESP32, so we save space on the device.

If anyone needs the other files on a more capable device (aka PC),
simply do a git clone.
