Asking validation during runtime are useless

[Hedroed]

Validation requests during execution are useless and can be annoying. So I propose to write only a message in the console to inform the user.

Moreover it is completely useless and redundant to ask for confirmation for the --fast option because the user has already taken the decision to add the option to this command.

You can see an example of using stringcheese on a 1MB file with the --fast option. I precise than the executing took less than a second.

stringcheese FLAG{ --file 1mb_file.bin --fast
Warning, with --fast your files will be treated faster by ignoring some tests so you might miss some flags. Do you wish to continue? (y/N) : y
This is a large file and may take a long time to be treated, do you wish to continue? (y/N) : y
MATCH FOUND! In stream, using encoding base10_ascii:
FLAG{the_flag}
