bug: rgba with alpha channel to any color conversion works, but neither hexa nor hsla

[NikarashiHatsu]

This issue is pretty much straightforward, to give you a picture of what went wrong, here I listed all of my issues

[WORKING] Rgba with opacity to any color conversion:

<?php

use OzdemirBurak\Iris\Color\Rgba;

$color = new Rgba('rgba(239, 68, 68, 0.5)');

?>

<div style="width: 200px; margin-bottom: 16px;">
    <?= print_r($color) ?>
</div>

<div style="display: flex;">
    <div style="width: 100px; height: 100px; padding: 16px; word-wrap: break-word; background-color: <?= $color->toHex() ?>; margin-right: 10px;">
        <?= $color->toHex() ?>
    </div>

    <div style="width: 100px; height: 100px; padding: 16px; word-wrap: break-word; background-color: <?= $color->toHexa() ?>; margin-right: 10px;">
        <?= $color->toHexa() ?>
    </div>

    <div style="width: 100px; height: 100px; padding: 16px; word-wrap: break-word; background-color: <?= $color->toHsl() ?>; margin-right: 10px;">
        <?= $color->toHsl() ?>
    </div>

    <div style="width: 100px; height: 100px; padding: 16px; word-wrap: break-word; background-color: <?= $color->toHsla() ?>; margin-right: 10px;">
        <?= $color->toHsla() ?>
    </div>

    <div style="width: 100px; height: 100px; padding: 16px; word-wrap: break-word; background-color: <?= $color->toRgb() ?>; margin-right: 10px;">
        <?= $color->toRgb() ?>
    </div>

    <div style="width: 100px; height: 100px; padding: 16px; word-wrap: break-word; background-color: <?= $color->toRgba() ?>;">
        <?= $color->toRgba() ?>
    </div>
</div>

[Buggy] Hsla with opacity color conversion:

<?php

use OzdemirBurak\Iris\Color\Hsla;

$color = new Hsla('hsla(150,100%,50%,0.7)');

?>

<div style="width: 200px; margin-bottom: 16px;">
    <?= print_r($color) ?>
</div>

<div style="display: flex;">
    <div style="width: 100px; height: 100px; padding: 16px; word-wrap: break-word; background-color: <?= $color->toHex() ?>; margin-right: 10px;">
        <?= $color->toHex() ?>
    </div>

    <div style="width: 100px; height: 100px; padding: 16px; word-wrap: break-word; background-color: <?= $color->toHexa() ?>; margin-right: 10px;">
        <?= $color->toHexa() ?>
    </div>

    <div style="width: 100px; height: 100px; padding: 16px; word-wrap: break-word; background-color: <?= $color->toHsl() ?>; margin-right: 10px;">
        <?= $color->toHsl() ?>
    </div>

    <div style="width: 100px; height: 100px; padding: 16px; word-wrap: break-word; background-color: <?= $color->toHsla() ?>; margin-right: 10px;">
        <?= $color->toHsla() ?>
    </div>

    <div style="width: 100px; height: 100px; padding: 16px; word-wrap: break-word; background-color: <?= $color->toRgb() ?>; margin-right: 10px;">
        <?= $color->toRgb() ?>
    </div>

    <div style="width: 100px; height: 100px; padding: 16px; word-wrap: break-word; background-color: <?= $color->toRgba() ?>;">
        <?= $color->toRgba() ?>
    </div>
</div>
