Protobuf only create whats needed

[AsherGlick]

Reduced from an exponential growth, and a random metric of:

The taco parse function took 2476 milliseconds to run
The protobuf write function took 37937 milliseconds to run

to a more linear growth, and the same metric of:

The taco parse function took 2494 milliseconds to run
The protobuf write function took 6735 milliseconds to run

The new system is now much more linear with output size as the entire sum of all the markerpacks are not being copied in memory for each output file anymore.
