Bitwise precedence is wrong

[fabi321]

Looking at parser/Lua.g4, it seems that the assumed bitwise priority is above multiplication, while it is in fact below concat reference on operator precedence. This is also the case in a small example. In a lua 5.4 console:

> 1&2+3
1
> (1&2)+3
3

The parsed tree for "1&2+3":

AddOp: {} 3 keys
  left: {} 3 keys
    BAndOp: {} 3 keys
      left: {} 2 keys
        Number: {} 2 keys
          n: 1
      right: {} 2 keys
        Number: {} 2 keys
          n: 2
  right: {} 2 keys
    Number: {} 2 keys
      n: 3
