ClearBit clears the bit at index `i` in the byte slice `b`, i.e.

MakeBitVector allocates a byte slice of minimal size that can hold numberBits.

MinimalByteSliceLength returns the minimal length of a byte slice that can store n bits.

ReadBit returns the bit at index `idx` in the byte array `b` (big endian) The function panics, if the byte slice is too short.

SetBit sets the bit at index `i` in the byte array `b`, i.e.

WriteBit assigns value `v` to the bit at index `i` in the byte array `b`.
