* Add `current_bit_offset()` and `read_bits(...)` to `std::mem` * Replace deprecated BitfieldOrder enum values with new clearer names This adds new options named `MostToLeastSignificant` and `LeastToMostSignificant` to replace the old `LeftToRight` and `RightToLeft` names. These names should be much clearer about what they affect and how. * Throw errors when `std::core::(get|set)_bitfield_order()` are called * Update all patterns to work with the new bitfield behaviors
