Allow reading FixedBitArray(...) without having to type ".get".

This works only for reading, as we can't return a reference to a single bit.
Also, [x][y] doesn't work either: FixedArray can return a column vector
which then can be dereferenced further, bit arrays here are packed so
returning a slice would require a whole new class.
