* fix(bits): prevent BitArray.UnmarshalJSON from crashing on 0 bits in the JSON (backport cometbft#2774) (cometbft#2778) This change fixes a bug in which BitArray.UnmarshalJSON hadn't accounted for the fact that invoking NewBitArray(<=0) returns nil and hence when dereferenced would crash with a runtime nil pointer dereference. This bug was found by my security analysis and fuzzing too.
