Ranges: interpretations are displayed incorrectly

[tomusdrw]

In hex mode:

• every i8 and u8 should be just one byte (i.e. 0xXX)
• every i16 and u16 should be exactly two bytes (i.e. 0xXXXX)
• every x24 should be 3 bytes
• every x32 should be 4 bytes
• every x64 should be 8 bytes

In dec mode:

• rendering 000 makes no sense. It's just 0.
• negative values should be just negative values, 0-1 is incorrect.
