Child task of #1

User input needs to be validated:

Make sure the input file exists
Make sure the output file does not exist. In case it does, warn the user about the fact that it is about to be overwritten

In case the input file does not contain a hidden message:

Make sure the message file exist
Make sure the message file size is $\lt 2^{32}$ bytes-long

In case the input file already contains a hidden message:

Make sure the message file does not exist. In case it does, warn the user about the fact that it is about to be overwritten

If we're able to implement a variable number of bits to change per color:

Make sure the number of bits $n$ is $1 \leq n \leq 8$, and $n$ is a power of 2
