Display binary data in a nicer way or trim

[edrozenberg]

Some of the boot option values set by my motherboard show as gibberish in efibootmgr -v. I'm assuming it's because those entries contain binary data.

It would be great if efibootmgr could display that data in a more user friendly way (unless the intent is to show the binary data as is for some purpose). Or otherwise to show only the data that makes sense to a user and not show the rest.

Example of what I'm seeing:

$ efibootmgr -v

BootCurrent: 0000
Timeout: 1 seconds
BootOrder: 0000,0001,0003,0005,0006,0007

How does https://github.com/vathpela/efibootmgr-devel/commit/bae00c1587b85b3d31353c0a52c845c3dc4ddb20 seem to you?
