Change data structure of profiles to bitfields

Browse Source 
- allows to express 'none' or 'all' more easily than lists
- more compact and easier to declare statically
- easier to check too

Only drawback: if we ever have more than 32 curves, we'll need an ABI change to
make that field a uint64_t.
