Find method not able to specify starting find from 1 level below

[HongyiFu]

Expected behavior and actual behavior:

In jQuery, you can do $el.find("> div") to match only div elements 1 level below current. Following from this, if we write $el.find("> div > p"), we can match <p> elements that are grandchildren of the current element.

This doesn't seem possible with jOOX, as this stacktrace is produced.

Exception in thread "main" org.joox.selector.ScannerException: Bad input!
    at org.joox.selector.Scanner.scan (Scanner.java:1889)

    at org.joox.Impl.find (Impl.java:488)
    at org.joox.Impl.find (Impl.java:81)

Are there any alternatives to do this other than chaining children method $el.children('div').children('p')?

Steps to reproduce the problem:

As above $el.find("> div > p")

Versions:

• jOOX: 2.0.0
• Java: 17

Thanks for your suggestion. That would be an interestnig improvement to the CSS2XPath utility:
https://github.com/jOOQ/jOOX/blob/main/jOOX/src/main/java/org/joox/selector/CSS2XPath.java

If you have some time, why not give it a shot? I'll be happy to review your PR.

Alternatively, note that the CSS selector support is just convenience. You can always just use Match::xpath instead, i.e. `$el.xpath("./div/p"). Usually, you'll get farther with XPath than with CSS selectors.
