Specify any value for "height" and/or "width" options in layout file are all acting as 1.

Hi, I really love this project since there are a lot of customization available, but I found one small problem.

According to man 5 wlogout:

height and width are values between 0.0 and 1.0 that control the location of where text is displayed the default width 0.5, height 0.9
avalible

But from my testing on wlogout 1.2.2-0, installed via pacman on Arch and hyprland, setting any value for "width" will place the text to the right side; any value for "height" will place the text to the bottom.
For example, the following layout file (which is default layout + "width" : 0.5) with default style.css will produce the following result.

{
    "label" : "lock",
    "action" : "loginctl lock-session",
    "text" : "Lock",
    "keybind" : "l",
    "width" : 0.5
}
{
    "label" : "hibernate",
    "action" : "systemctl hibernate",
    "text" : "Hibernate",
    "keybind" : "h"
}
{
    "label" : "logout",
    "action" : "loginctl terminate-user $USER",
    "text" : "Logout",
    "keybind" : "e"
}
{
    "label" : "shutdown",
    "action" : "systemctl poweroff",
    "text" : "Shutdown",
    "keybind" : "s"
}
{
    "label" : "suspend",
    "action" : "systemctl suspend",
    "text" : "Suspend",
    "keybind" : "u"
}
{
    "label" : "reboot",
    "action" : "systemctl reboot",
    "text" : "Reboot",
    "keybind" : "r"
}

As the pictures shows, the text "Lock" is placed to the right side (which I assume is value 1). Not sure can anyone reproduce that.

I also discovered the same thing: when you specify a width in the layout file, you will see the text shifted in the right side

                    fprintf(stderr, "Invalid height\n");
                }
                else
                {
                    buttons[num_buttons - 1].yalign = buffer[tok[i].start];
                }
            }
            else if (strcmp(tmp, "width") == 0)
            {
                if (tok[i].type != JSMN_PRIMITIVE ||
                    !isdigit(buffer[tok[i].start]))
                {
                    fprintf(stderr, "Invalid width\n");
                }
                else
                {
                    buttons[num_buttons - 1].xalign = buffer[tok[i].start];
                }
            }
[...]

the values are being incorrectly assigned to the ascii code of the first character of the token

buttons[num_buttons - 1].yalign = buffer[tok[i].start];

buttons[num_buttons - 1].xalign = buffer[tok[i].start];

i made a fix in #63
