Add a max number of records to load

[JoolsMcFly]

Hi!

We have a use case where we need to only load the first N records of a file.

It's currently not supported but the change could be minimal.
So in \PhpMyAdmin\ShapeFile\ShapeFile::loadRecords we would need to change

$this->records[] = $record;

to

$this->records[] = $record;
if (count($this->records) >= $this->maxRecords) {
    break;
}

$maxRecords could be initialized to a large value or accept int or bool and code would be

$this->records[] = $record;
if ($this->maxRecords && count($this->records) >= $this->maxRecords) {
    break;
}

Thoughts?

yes, why not. I prefer to avoid counting multiple times
If you add tests for it, then for me it should be okay at PR review time
