fix jump and branch destinations.
note: branching is no longer compatible with CajeASM.
make LUI dumb: only use 'UPPER' with LI/LA.
note: this is very incompatible with CajeASM.
add LUUI pseudo-instruction to use 'UPPER' instead of 'LOWER'.
fix SUBI/SUBIU parsing.
fix LI for values under 0x10000.
pass filename through main().
tell Lexer our filename.
don't print filename in Dumper since it's irrelevant.

new dumper to support directives
...
the old one could still have a place,
with its simplicity and speed.
also, screw versioning.

define formats in the instruction table
...
this greatly reduces code bloat,
and made it easier to implement a few instructions.
everything is still very untested, however.
