v2.0.0

Bug Fixes

• fix Infinity speed that would happen when data was read on same ms (2a6edfd)

Code Refactoring

• use const, let (30f2fe6)

Features

• toHuman(0) now returns "0B" (ad9350c)
• add precision option to toHuman() (27917b7)
• add StreamSpeed#getSpeed() to get current speed (868f2e9)
• add StreamSpeed#getStreamSpeed() (04603bb)
• default to calculating speed over a range of time (595d0ce)

Performance Improvements

• improve performance when adding/removing streams (66952bd)

BREAKING CHANGES

• • new StreamSpeed(timeUnit) - new StreamSpeed({ timeUnit })

• Speed is now calculated based on total data read over a range of
  time, defaults to 1sec. Previously there were 2 speeds, current speed
  and average speed. Current speed was calculated based on amount of
  data received in latest read over the time difference between latest
  read and last read.
• speed event now only emits one speed.

• toHumman(timeUnit) -> toHuman({ timeUnit })
• const, let not supported in node < 6
