reddisassembler v3 [rebirth]

rewritten again, was bored and forget about the rewrite so this kinda just sat around on my desktop for 2-3 months.

changes from original

deserializer:

deserialization was actually added (original depended on lbi.lua)
- deserialization is mainly based from lbi.lua with some modifications.
deserialization now has settings for things like instruction bits. (lua obfuscators tend to use lbi and change the bytecode around) disassembler:
disassembler now has an instruction lookup table.
disassembler has register field sorting (so it displays only the used registers).
disassembler now supports jump lines ->
- jump lines support going backward (this took me a while until i realized i was dumb.
- added instruction addresses.
- prototypes will be referenced by addresses as prototype names are almost never in the bytecode. textstream:
textstreams were finally implemented allowing me to do column text properly without any hastle.
this allows for organized output from the disassembler with equal spacing all the way through.
sadly the old jump line characters were not working kindly with the textstream so i had to compromise on the '+---', 'o-->' and '|' lines for showing jump lines.
added some new stuff to the textstream to allow support for backwards jumping also made a hacky method in the disassembler.

output

feeding the disassembler the bytecode of:

if 1 == 2 then
	print('hi')
end
print('noob')

will reward you with the following disassembled code formatted beautifully.
