Not much new here. Just an option to force mp3gain to assume that all input files are genuine mp3 files.

Early on in the program development, I had a few people who had problems with a few files. It turned out that they were running mp3gain on some mp2 files that had been mis-named as mp3 files.

I put in some code to check for this case, but my code turns out to be a little too sensitive to mp3 files with corruption right at the beginning of the file. In other words, a valid mp3 file that has an invalid frame at the very beginning can get misidentified as an mp2 or mp1 file.

Instead of putting more effort into doing a more thorough check of the file, I just stuck in an option to skip the check altogether. In theory, this enables a user to run mp3gain on mp2 files, which will screw up the mp2 file, but at least the user will have to consciously enable that option.
