Binary file features?

[Ergus]

Hi all:

If there is a binary file with known format (ie, it was somehow saved
form C++ or numpy) nothing extremely complicated something like an array
of structs, or a header+payload of known data...

Do we have anything in elisp to visualize the data in some user-friendly
way? (after providing some information about the format somehow?)

Thanks in advance,
Ergus
