Minimalistic Odin formatter.

• Indents lines with 1 tab per scope level
• Does not indent when blocks
• Leaves the contents like multi line strings and multi line comments untouched
• Adds one indent level to parameters if they were broken up into multiple lines. example:

input:

	fmt.printfln("%v %v %v",
	a,
	3,
	5
	)

output:

	fmt.printfln("%v %v %v",
		a,
		3,
		5
	)
