Get encoded mapping scheme as a single value for storage purposes.  This scheme value 
identifies the ratio of mapped bytes to source bytes.  Value is encoded as two 7-bit 
values corresponding to the destination and source byte counts.
@param schemeDestByteCount number of mapped bytes per mappedSourcebyteCount (1..127).  This 
value must be less-than or equal to schemeSrcByteCount.
@param schemeSrcByteCount number of source bytes for mapping ratio (1..127)
@return mapping scheme value
@throws IllegalArgumentException if invalid mapping scheme specified
