Compression: Terminate workers after use

Browse Source 
While the browser engine can clean up workers automatically, it's a good
idea to terminate them as soon as we don't need those anymore. It's
generally suggested to reuse a single worker for repetitive operations,
but implementing such a system is much harder. In addition, spawning a
new worker for each operation allows (de)compressing multiple blobs in
parallel :)
