Unpacked BCD to 16 bit binary conversion

; Input: unpacked BCD in  tenk:thou:hund:tens:ones
;Output: 16 bit binary in hi:lo
;  Size: 35 instructions
;Timing: 2+34+2=38 instruction cycles
; Notes:
;1) if input is higher than 65535 output is meaningless
;2) algorithm synopsis:
;> dec2bin([1 10 100 1000 1e4], 16)
