Remove byteorder dependency

[psychon]

The Rust standard library includes some byteorder-like helper functions for a while already. This commit replaces the use of byteorder with these helper functions.

---

I have no particular reason for this except for trying to remove a dependency. byteorder is not a "bad" dependency, but it still seemed unnecessary to me to do what is being done here.

Feel free to tell me that this is not worth it. :-)

Changes look innocuous. In general I'm in favor of removing dependencies if the replacement is trivial logic.

For my own curiosity I want to go back and check commit history later to check the commit that added the dependency to see if there's any additional context.

to check the commit that added the dependency to see if there's any additional context.

git log --reverse -p -S byteorder says this was added in commit 4ba7873. That commit adds the dependency, but makes no use of it?!

Commit e9fe26a adds it as extern crate, but still makes no use of it.

The first real use appears in commit 6953a23 in a function convert_to_new_format(). It is used to convert [u32; 4] to [u8; 16] in little endian.

Dunno...

Ha that was quick -- thanks for checking.
