Format description is wrong

This is clearly wrong as can be seen by any annotations file, for example 000205.tsv:

class   xtl ytl xbr ybr temporary   occluded    data
3.2 702 979 730 994 false   true    
2.4 16  946 26  975 false   false   
4.1.2   23  948 32  975 false   false   

The relationship is reversed, br is always bigger than tl.
