shell doesn't have to be slow, but C will usually be faster.

Code:
od -An -t x1 -v yourfilename.bin |
 tr -s 'a-f ' 'A-F\012' |
 (echo 16;echo i;echo 2;echo o;sed -e 1d -e 's/^/F/' -e 'a\p') |
 dc -f - |
 sed 's/^1111//' |
 tr -d '\012'

(not totally convinced I know that the OP is wanting though)
