IIRC we now have the VSA sources available, so we should be able to
build a custom VSA.

For storing the VSA in the LAR, I have to know a few things.
- Is the VSA a blob with no header and/or signature?
- Do we have to load it at a specific address?
- How do we determine the entry point?
- What's the exact calling convention?

If at all possible, I'd like to handle the VSA like any ELF file in the
LAR, that means parsing and compressing it for storage in flash, then
uncompressing and loading it to a specified address and executing it at
the specified entry point.
