Error compiling with Swift 6.2

[sbeitzel]

It seems that the way Data exposes its underlying bytes has changed with Swift 6. Now, rather that having Data.bytes expose a [UInt8] it gives us a RawSpan.

This shows up in a few places in the library.

Hey @sbeitzel, thanks for posting this issue. Going through and updating all of the swift-libp2p repos for swift 6+ is on my October todo list.

If you'd like some help with that, I've got a few cycles to spare. I wouldn't jump on PR #28 just yet, since merging it would probably break all the builds that depend on this library. I'm coming at this by just trying to build the LibP2PChatExample app, to see if libp2p will serve my needs for my applications.

Hey thanks for the offer and the PR, I've been slowly updating the libp2p packages over the last few days. I still have a couple more to go but hopefully I'll have the LibP2PChatExample app up and running again soon.
