get_throttled for humans

vcgencmd get_throttled is a command on Raspberry Pi operating system, Raspbian, to find out whether the processor has been throttled due to overheating or under-voltage, and whether this is still the case.

Unfortunately, the format of the output is represented is hexadecimal, so I wanted to write a simple script that would help to translate this into plain language.

Only runs on platforms, where the command above is legit.
