Setting indentation to false does nothing

[Diegovsky]

Describe the bug

Setting the value to false does not, in fact, disable indentation.

Version and Installation Info

• toml.lua version: 0.4.0-0
• Operating system: Arch Linux x64
• Installation method: luarocks

To Reproduce

Minimal lua script:

local toml = require'toml'

toml.encodeToFile({
  base = {
    val = 'val',
    nested = {
      nval = 'nval'
    }
  },
}, {file = 'ex.toml', overwrite = true},
  {indentation = false})

Expected behavior

I expeted no indentation to occour.

Additional context

I tried setting the other listed flags to false too. Nothing worked.
