Hm....I was assuming little endian format and that's why the byte is written to [0] with zero_extend_byte but maybe it should be at the end like from_u8?

The C test doesn't work either way probably because there are more bugs. But write is working so perhaps I should indeed use from_u8. If so we should remove zero_extend_byte.

And also then I should change sign_extend_byte. I pushed a commit. Test still not working.

Checked that words in memory are stored in big endian format.
