[BUG] First line of text is centered when content align is non-centered

[nedpals]

Describe the bug
When the ContentAlign is set to Left/Right and the TitlePos is not set to Inside, the first line of the content is still aligned to the center.
To Reproduce

package main

import "github.com/Delta456/box-cli-maker/v2"

func main() {
     bx := box.New(box.Config{
             Px: 2, 
             Py: 0, 
             Type: "Single", 
             ContentAlign: "Left", 
             Color: "Green", 
             TitlePos: "Top"
     })
     bx.Print("System Info", "Lorem Ipsum\nfoo bar hello world\n123456 abcdefghijk")
}

Expected behavior
The first line of the content should be aligned based on ContentAlign.
