Create separated files for directory file-entities

[alfsb]

This PR partially reverts #213 , re-enabling the creation of separated files for directory file-entities.

Per documentation, LIBXML_PARSEHUGE:

Sets XML_PARSE_HUGE flag, which relaxes any hardcoded limit from the parser. This affects limits like maximum depth of a document or the entity recursion, as well as limits of the size of text nodes.

Even being a very old option (since libxml 2.7.0 / PHP 5.3 eras), it is insufficient for PHP manual building, in some OS and libxml versions. Until there is something like a truly LIBXML_PARSEUNLIMITED, PHP Manuals will soon become unparseable.

@leonardolara , please test this. I think it may fix the Maximum entity amplification factor exceeded error.

As side note, as Portuguese language is more verbose than English, the pt_BR manual is particularly susceptible to the "entity amplification" error:

Ok, now it's building again. Nice work!

Nice to hear that. I will try test this on Windows, before merging it. Testing by other people would be nice, too, as this is an intermitent error, that only occurs in some PHP/libxml versions.

Local tested on Win 10, PHP 8.3.14. Merging.
