Random number seed is always the same on the simulator

[microbit-matt-hillsdon]

This does't match the device and is unhelpful when teaching random numbers.

We need to implement this stub:

micropython-microbit-v2-simulator/src/microbithal_js.c

Line 392 in b88271f

// This is needed by the microbitfs implementation.

Despite the comment, it's only used for the seed in the port config.

We dug into this a bit, and despite CODAL having a random number generator, MicroPython uses its own seeded from CODAL's one (potentially reseeded by the user).

Looks like we had a case of:

I looked into the other comments from the StackOverflow question:

random.seed doesn't work in the simulator

This seems to work for me, please raise a new issue with an example program if you can reproduce. For the moment, until we fix this issue, the default seed is zero to setting it to that won't affect anything.

machine.reset seems to freeze on the emulator. Will be updating with solution after I test with microbits

This doesn't reproduce straightforwardly, however trying variations on the program on stackoverflow, I raised #86

[microbit-matt-hillsdon]

The random seed issue is fixed by #87.

For this change to be available in the Python Editor V3 we still need to release the simulator. I'll do this once we've had a chance to look at the related issue #86.

This change is now live in the V3 Python Editor as part of simulator 0.1.6.
