speed optimized version of targetCBlockSize

note that the size of individual compressed blocks will vary more wildly with this modification.
But it seems good enough for a first test, and fix the speed regression issue.
Further refinements can be attempted later.

* `--target-compressed-block-size=#`:
Attempt to produce compressed blocks of approximately this size.
This will split larger blocks in order to approach this target.
Notably useful to improve latency when the receiver can make use of early data sooner.
This feature is notably useful for improved latency, when the receiver can leverage receiving early incomplete data.
This parameter defines a loose target: compressed blocks will target this size "on average", but individual blocks can still be larger or smaller.
Enabling this feature can decrease compression speed by up to ~10% at level 1.
Higher levels will see smaller relative speed regression, becoming invisible at higher settings.
