This CLI currently reads the input data as a byte array. This is simple and allows for ensuring all data is read into a memory, reducing disk overhead during the preformance command. However, this means the CLI is limited to the maximum size of an array, which is INT_MAX. In order to support the CLI parsing/unparsing larger files, we should instead work on InputStreams rather than array buffers. For the performance subcommand, this will mean requiring something like a SplittalbeInputStream that will allow multiple consumers of a single InputStream.

Some SplittableInputStream implementations do exist, for example in JMRTD and on stack overflow, but licensing issues make it so these aren't an option. Either need to find a solution compatible with our license or implement our own.

This work should be done concurrently with changes to improve the efficiency of the I/O layer.
