The maximum length of escape_sequence is 21 bits, so adjust limit in
code to match this.

Up to 10% faster on Cortex-A8.

this makes the 9/7 C wavelet at the decoder side 22% faster.
The old code is changed to match the new in terms of the order of operations
(which also makes it sligtly faster)

8% faster C 5/3 wavelet at the decoder side.
