Add support for 6800 compatibility instructions. The occasional program uses the 6800 compatibility instructions since they are actually specified by Motorola in at least some documentation. They advertised the 6809 as source compatible with the 6800. This mode is not enabled by default, however. It is my belief that receiving an error when using a non-6809 instruction is more useful since it is unlikely that much 6800 source code is being assembled for the 6809 these days. Nevertheless, the --6809compat option is present for just those purposes so one does not have to resort to using macros (which would work equally well in most cases).

>This human-readable ASCII hexadecimal format consists of CR+LF terminated 
lines of ASCII text. Each line has the following structure: a zero-padded 
four-digit ASCII hex address, a colon separator, and one or more zero-padded
two-digit hex values separated by commas. ASCII Hexadecimal format favors 
paragraph-aligned addresses (i.e. a least significant address nybble value
of zero). During output, the number of hex values on each line are adjusted
to align the address of the next line on a paragraph boundary. The sequence 
of addresses in the ASCII Hexadecimal file directly follows that of the source
file; multiple ORG directives in the source code may result in out-of-sequence
addresses in the ASCII Hexadecimal output.</P

>LWASM can output this format since version 4.10.</P
