If you're encoding numbers to strings, and viceversa, that's ok.
If you also need to support encoding strings (as bytearrays) that
didn't work for me.

I like your approach, it was more concise and didn't require reversing
the output as the one i used [1]

I guess, every bit and byte operation is simpler when happens in
multiples of 8 :)
