  - precision -- The data of the HyperLogLog is stored in an array of m registers. m is 2^precision, e.g. precision=4, m=16. The precision should be between 4 to 16.
  - TIME -- Optional. Creates a time-limited HyperLogLog. 'window-milliseconds' specifies the duration of the time window in milliseconds. This mode allows HyperLogLog to estimate the cardinality of items within the range (now - window-milliseconds, now].

+The HLL has a relative error of 1.04/sqrt(m), where m is the number of registers. The SwarmKV HLL implementation uses 6 bits per register, so for a key with precision=14, the memory size is ~12KB (2^14*6/8 bytes), and with a standard error of 0.81%.
