25eab76c95 Fixed Merlin LNK directive and streamlined the LINK directive
- No longer merging sections but assigning sequential addresses to
sections
- Required separate linking logic for Merlin.

90fc74a6fb Adding -org command line option
- -org allows for command line control of fixed address binary output
start address
- fixed a quirk in merged section reloc resolve

b5ab013cb5 Rebuilt the fixed address linker
- Code and data segments are not just merged together, each segment in
each export group just gets address assigned and relocs / labels are
fixed up.
- BSS sections won't generate binary data if not inbetween code and data
segments for an export group (labels and relocs are still extended)
- DC directive now allows for .t (3 byte values) and .l (4 byte values)
decoration
- .lst includes all section info and address ranges if fixed
- Updated x65 dump tool with fixes to x65 data

9f935a8e91 Bug fixes
- REPT caused a crash if expression was resolved after assembly
completed
- Fix expression % as a label at end of scope if another scope ended
before the current scope
- Removed # from conditionals since that doesn't fit with any assembler
style
- Added .l (long) and .t (triple) to label pool sizes, also supporting
.d as double which is the same size but different meaning than .w (word)

95e22ae7a2 Fix for forward reference in REPT block and assigning section relative address to symbol
- Remember the REPT index for values that can't be evaluated yet
- Remember section reference when evaluating symbols dependent on
address labels.

extra counting labels.
- "<<" got interpreted as a right shift
- Added LONG keyword to declare 32 bit values
