Prevent merging default array values by default

[colinodell]

• bug fix / new feature (#13, #24, https://github.com/nette/schema/pull/28#issuecomment-712131718)
• BC break? yes
• doc PR: nette/docs#???

This is an alternative to #28 which always prevents default array values from being merged with user-provided ones.

@dg As a project maintainer myself, I really hate to be that guy, but... do you have a rough ETA on if/when this change (or something like it) might be released? This functionality is going to be essential for league/commonmark's upcoming 2.0 release so I'm trying to plan whether we should wait on a nette/schema release that doesn't merge defaults, or if we should forge ahead with some kind of alternate approach for now (maybe a fork or compatibility layer or something like that).

I completely understand that you have your own personal and professional priorities, so the last thing I want to do is pressure you into making a decision or doing extra work, but any high-level guidance you could offer me would be much appreciated!

:-D

I've had a lot of work to update all my libraries to PHP 8 last month, and now I'm ready to finish new releases, so the new version will be really soon.

That works for me. I'll keep an eye out for that release whenever it lands - no rush here. Thanks for the quick response and for the work you're putting into this - I greatly appreciate both!

And I do know this PR has fallen out of date, so let me know if you'd like me to rebase/recreate it - happy to do so if it helps.
