refactor(filter-stream): Refactor & optimize FilterStream #27

Closed jhermsmeier closed 7 years ago

jhermsmeier commented 7 years ago

Changes:

Add FilterStream benchmark
Add debug output to FilterStream
Generate pre-processed ranges to simplify range bounds checking
Optimize _transformBlock() to only slice & dice chunks that don't adhere to the block size, also improving performance considerably by causing fewer operations on buffers
Fix _flush() to emit correctly transformed blocks
Update emitted blocks check in tests

Change-Type: minor

jhermsmeier commented 7 years ago

I have now also added comments throughout the methods, and added some missing doc blocks, to hopefully make it easier / quicker to grasp what's going on in there.
