Feature request: Add RegexPhraseQuery support

[CharlesNg35]

Hi, thanks for the great work on this library!

I'd like to request bindings for two query types that aren't currently exposed:

RegexPhraseQuery — phrase search where each word can be a regex pattern, with slop support. Really useful for fuzzy phrase matching
(e.g. "apocal.* 10"~25 matching "apocalypse 10" or "apocalyptique 10"). Right now there's no way to combine phrase proximity with pattern
matching using the available APIs.

Rust docs: https://docs.rs/tantivy/latest/tantivy/query/struct.RegexPhraseQuery.html

PhrasePrefixQuery — phrase search where the last word is treated as a prefix. Great for autocomplete (e.g. "apocalypse di" matching
"apocalypse dix" or "apocalypse divine").

Rust docs: https://docs.rs/tantivy/latest/tantivy/query/struct.PhrasePrefixQuery.html

Would love to see these added when you get a chance. Thanks again!

Hi @CharlesNg35,
does tantivy-py also have the APIs exposed. Then we could have similar interface.

I took a quick look, and it seems that it doesn’t, @oxdev03.
