Deserializer changes broke bytecode interpretation

[qux-bbb]

test.lua:

hello = 'hello'
print(hello)
len = string.len(hello)
print(len)
the_num = 1 + 2
print(the_num)
float_num = 3.14
print(float_num)

mytable = {}
mytable.foo = "hello world"
mytable.bar = 1 + 2
print(mytable)

function sayhello(name)
    print("hello, "..name)
end

This command can generate Out.lua:

cargo run -- --file test.lua

Then I try to run Out.lua, the error:

$ lua ./Out.lua 
lua: ./Out.lua:1: attempt to perform arithmetic on a nil value
stack traceback:
    ./Out.lua:1: in function <./Out.lua:1>

It looks like I broke something when I swapped out the deserializer. I'll do my best to fix it this week
