Added defaultFilters to Livewire Datatables

[Cosnavel]

Added defaultFilters. The defaultFilters should be an Array of column names and the default filter value to use for.
When a persisted filter ($this->persistFilters is true and session values are available) is available, it will override the default filters.

Example Usage:

 
<?php

use App\Models\User;
use Illuminate\Support\Carbon;
use Mediconesystems\LivewireDatatables\BooleanColumn;
use Mediconesystems\LivewireDatatables\Column;
use Mediconesystems\LivewireDatatables\Http\Livewire\LivewireDatatable;
use Mediconesystems\LivewireDatatables\NumberColumn;

class UsersTable extends LivewireDatatable
{
    public $defaultFilters = [
        'deleted_at' => '0',
    ];

    public function builder()
    {
        return User::query()->withTrashed();
    }

    public function columns()
    {
        $columns = [
            NumberColumn::name('ID'),
            BooleanColumn::name('deleted_at')->filterable()->label(__('Deleted')),
        ];

        return $columns;
    }
}

Would love any feedback and review on it 😊

Looks good to me. Could you please add a line to CHANGELOG.md and a small documentation block/example into README.md and i will merge it. And do a new release.

Thanks a lot !

@thyseus added some documentation for the Readme. Does this work for you? What do you expect for the Changelog? Currently, there's not much into there 😛

[thyseus]

Very good. Thanks a lot for your contribution !

[Cosnavel]

@thyseus when do you plan to release the next tag?
