[GEMPAK #ZHN-334043]: LAMP decoding

Correction: for the 2.5km LAMP, the WMO header regex match will be

^[LM][CDEF]U... KWNO

I previously had it as 

^[LM][CD]U... KWNO



> # LAMP 2.5km
> NGRID   ^[LM][CD]U... KWNO
> PIPE    dcgrib2 -v 1 -d data/gempak/logs/dcgrib2_lamp.log
> -e GEMTBL=/home/gempak/NAWIPS/gempak/tables
> data/gempak/model/mos/YYYYMMDDHH_lamp.gem
