`memory.readbyterange` will now return partial data if the requested range
extends beyond the domain (invalid addresses are read as 0). Did not fix docs of
`memory.readbyterange` which incorrectly claim the returned table uses the
memory addresses as keys i.e. addr..(addr+length) - it was and remains
0..length. `memory.write_u8` will now check the specified domain's length and
not erroneously check the selected domain's length.
