show bytes as hex on all supported platforms

[evant]

• bytes are shown as hex on all platforms that support them (0x00)
• ~shorts are shown as hex (0x0000)~

~note: I'm a bit less sure about the short hex representation, it's a convenient way to make sure it displays uniquely but I don't know if it's the best display format for how they are used in practice~

495

If we don't want hex display of shorts #499 may be a better solution there ex:

expected:<4> with type:<class kotlin.Int> but was type:<class kotlin.Short> with the same string representation
