* Replace sys::vga::clear_screen() by csi code * Replace all remaining calls of vga functions by csi code * Remove dead code * Add some guard clauses * Add TODO on partially implemented CSI codes * Fix inverted params on cursor position * Print newline char between lines * Add a TODO to load a palette via ANSI OSC commands * Move cursor after clear screen * Simplify line insert * Fix old bug when scrolling twice the screen width * Simplify backspace code * Disable interrupts when printing in serial * Refactor status line * Hide cursor during printing * Avoid printing status line over saving status * Use 1-indexed rows and cols in the user interface
