Improve LcThread Formatting

[CuriousTommy]

I figured out how the CLI tool handles outputting the values from a list.

The following code changes modifies the output from this:

  [12] cmd: LC_UNIXTHREAD cmdsize: 288
    |*flavors: [LcThreadFlavor { flavor: 6, count: 68 }, LcThreadFlavor { flavor: 30, count: 16 }]

to this:

  [12] cmd: LC_UNIXTHREAD cmdsize: 288
    |*Flavors: 
     |*flavor: 6
     |*count: 68
    --------------------
     |*flavor: 30
     |*count: 16
    --------------------

Let me know if you need me to make any additional changes!
