There are no bit-fields provided in the proto definition language. if you
need these kind of things because you are conscious about the size on the
wire or stored size on disk, you need to use one of the fixed32 or fixed64
types and do it yourself.
If you are worried about the size in memory, I think the code generator
already attempts to use this to compact a set of boolean values in this way
in languages that support it (not 100% sure, would need to look at the code
again).
