Partial namespace support

[audriusnaslenas]

The plugin doesn't recognises partial namespaces. I have the setting " Clean up unused imports" turned on, so in this case

<?php

namespace PN\Entity;

use Doctrine\ORM\Mapping as ORM;

#[ORM\Entity]
#[ORM\Table(name: 'test')]
class TestEntity

the plugin removes the line use Doctrine\ORM\Mapping as ORM; and so breaks the code.

Full namespace works ok:

<?php

namespace PN\Entity;

use Doctrine\ORM\Mapping\Entity;
use Doctrine\ORM\Mapping\Table;

#[Entity]
#[Table(name: 'test')]
class TestEntity
{
}
