Fix incomplete Teehistorian chunks being written

Browse source 
Save/Load code are up to 65536 bytes long. However, Packer only has a
buffer of 2048 bytes. Writing SAVE_SUCCESS and LOAD_SUCCESS chunks
likely for saves with 3 or more tees.

This increases the buffer size for all packing including networking
packets and is therefore probably not the optimal solution. An
alternative would be to create an additional packer CLargePacker or make
the size a template argument.

The suggested change is the simplest fix adding not much complexity, but
increases the chance of overrunning the stack size. I'm open to take
another approach.
