Remove support for 8 or 16 bit BigInt words
It turned out 8 bit was very broken (failed to compile, due to
overload problems with functions taking uint8_t vs word).
16 bit words work aside from a test failure, but is really slow.
Practically speaking we are not in a position to support 16-bit CPUs
very well. And being able to assume sizeof(word) >= sizeof(uint32_t)
allows simplifying some code.
