Add option in zig fmt to set or customize max column length

[bauripalash]

Currently, there is no option (at least I couldn't find one) in zig fmt to customize the max column length; personally, I prefer 80, but zig fmt is doing its own thing.

I would like to propose a command line flag in zig fmt command to set max column width.

#1003 (comment) zig fmt so far has a policy of no options

commas can be used to explicitly delimit line breaks however,

var foo = [_]u8{ 0, 1, 2, 3, 4, 5, 6, };

will get subsequently transformed into:

var foo = [_]u8{
  0,
  1,
  2,
  3,
  4,
  5,
  6,
};

this works for array and struct initializers, function calls, function parameters, and more

specifically for arrays, grids are also possible. for instance the below is stable

var foo = [_]u8{
  0, 1, 2,
  3, 4, 5,
  6,
};

Thanks for the clarification.
