RFC: Make it much more customizable

[bernhardh]

I know this was part of the cleanup / make it easier some time ago (v1 I think), but why not work (optionally) with an objects instead of plain array structure? It would make customization (like in #127, #79, #72, #58) much easier. Something like this:

Tab::make("Tabs", [
    TabItem::make("My title", [
        ...Fields...    
    ]),    
])

where TabItem would be a new class of this package, holding the fields. To keep it backward compatible, you could also allow to use the "old" syntax with array key-values.

Why? The benefit of this would be, that you can extend and chain methods to each single tab. Please let me show you some examples:

#127 "How to customize a tab name in a URL?"

Tab::make("Tabs", [
    TabItem::make("My title (4711)", [
        // ...Fields...    
    ])->name("my-title"),    
    TabItem::make("Photos (2)", [
        // ...Fields...    
    ])->name("photos"),    
])

#79, #72 Icons

Or you could even implement a couple of other features, like icons:

Tab::make("Tabs", [
    TabItem::make("My title (4711)", [
        // ...Fields...    
    ])->icon("<svg....>"),    
])

But this isn't necessary to make it as a seperate method, if you don't want it. Just make the "title" html able and since we can now set the name seperatly, we could do it like so:

Tab::make("Tabs", [
    TabItem::make("<svg ...> My title (4711)", [
        // ...Fields...    
    ])->name("my-title"),    
])

#58 Conditionally show tabs

Only show tabs, if a condition is met. For example with the help of a callback:

Tab::make("Tabs", [
    TabItem::make("Show only if...", [
        // ...Fields...    
    ])->showIf(function() {
        // ....
    })
])

Style each tab separatly

Or even give the tab extra css classes, to have different colors for tabs, for example if you wanna make a tab red, because its a very important one or has some things to do on it:

Tab::make("Tabs", [
    TabItem::make("My title (4711)", [
        // ...Fields...    
    ])->cssBodyClass('my-cool-class make-it-red mx-5')->cssTabClass('make-it-red')
])

And many more ...

... the nice thing is, that you should or could make the TabItem macroable, so that each user of the package could extend it, if needed, by themself.

To keep it backward compatible

... you could allow also the "old" syntax and allow mixing:

```php
Tab::make("Tabs", [
    "Basic Fields" => [
        // ...Fields...    
    ],
    TabItem::make("Show only if...", [
        // ...Fields...    
    ])->showIf(function() {
        // ....
    })
])

I actually really love this idea. It would take a bit to implement and needless to say this will not be possible without actually adding some unit tests (which are also planned). I'll look into this.
