docs: Create a new bit condition that matches the provided bit string,
          with the indicated per-index wildcard probability.
  
          Usage:
              condition = BitCondition.cover(bitstring, .33)
              assert condition(bitstring)
  
          Arguments:
              bits: A BitString which the resulting condition must match.
              wildcard_probability: A float in the range [0, 1] which
              indicates the likelihood of any given bit position containing
              a wildcard.
          Return:
              A randomly generated BitCondition which matches the given bits.
