Make `OffsetAccess` properties private

[mspirkov]

I accidentally made the properties public. It's probably too late to fix it now, as it would break backward compatibility.
It might be worth fixing it in the second version.

TypeResolver/src/PseudoTypes/OffsetAccess.php

Lines 29 to 32 in 5a34952

	/** @var Type */
	public $type;
	/** @var Type */
	public $offset;

If necessary, I can do PR for the future.

I think it's ok right now to do this as a bugfix, it was never intended like this, and the change is just a day old?

Great, then I'll fix it now. Thanks
