Hla 809 chunking

[jacob720]

Added the ability to read and write a PB file in chunks. This may be useful for large files which cannot be loaded into memory all at once. This also allows someone to read just the header and first few lines of a PB file much more efficiently, for example through the aa-print-header entry point.
