[adland]

Add support for LEAD MCMW 2.0 Wavelet codec
downloaded from
http://www.leadtools.com/evaldownload/downloads.aspx?category=Codecs

dlls used are LCODCCMW2E.dll and LCMW2.dll

samples tested were made using their encoder tool under windows.
viewing or playback works

could this be inserted as a patch after a sanity test

thanks
