Hi, dear Guile users!

I'm using Guile to play around with some binaries. In Guile, the
bytevector prints its content in decimal format. Just like:

#vu8(255 255 255 255)

But, it's always more convenient if its content is printed in hex format
like

#vu8(#xff #xff #xff #xff)

I don't see any option to toggle this, What should I do to custom how
bytevector looks?

Thanks!
