ts: obsolete --sout-ts-bmin and --sout-ts-bmax

just as hinted in the option long descriptions, these options are actually obsolete, but were never converted to actual obsolete options

a little code was left that read, stored and reacted to the option values, however it really did nothing at all useful:

1. if min > max, gives warning and sets to zero - POINTLESS
2. if min or max > 0, gives error about not supported - POINTLESS
3. if bit rate goes above max, gives warning - POINTLESS
