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.
