I'm highly interrested since, from what I found, the CRC computing is different 
between Layers and Versions (the amount of data and the order).

I've added some improved CRC calculating code to lame (bitstream.c)
The code is takes 512 byte for a table and is much faster.

Overall performance improvement is nearly not measurable,
so I disabled this code. But for an mp3 checker this can be different ...
