Add Subtis provider for Spanish subtitles

[lndgalante]

Summary

@Nyaran requested support for Subtis in the following issue comment.

This PR adds a new provider for Subtis, a Spanish subtitle search service for movies.

Features

• Search by file size + filename (exact match)
• Fallback to filename-only search (fuzzy match)
• Spanish language subtitles only
• Movies only (no TV shows)

Changes

• New provider: SubtisProvider
• Tests with VCR cassettes
• Entry point in pyproject.toml

Test Plan

# Install in dev mode
pip install -e .

# Run tests
pytest tests/providers/test_subtis.py -v

# Test with a real file (example)
subliminal download -l es -p subtis "One.Battle.After.Another.2025.2160p.4K.WEB.x265.10bit.AAC5.1-[YTS.MX].mkv"

Expected output:
Collecting videos  [####################################]  100%
0 video collected / 1 video ignored / 0 error

Hi!

I tried the branch from this PR, and is not working for me:

With the movie "The Avengers":

That's probably correct @Nyaran but because we don't have that specific version. Showing a working example:

Avengers Endgame movie:
https://subtis.io/subtitles/movie/avengers-endgame-2019

Specific subtitle version (YTS 1080P):
https://subtis.io/subtitle/file/name/3234022377/Avengers.Endgame.2019.1080p.BluRay.x264-[YTS.LT].mp4

Let's use that as an example 👇
You can do touch "Avengers.Endgame.2019.1080p.BluRay.x264-[YTS.LT].mp4" and then run your same command: subliminal --debug download -f -l es . -p subtis -r metadata .

If you want to test search by bytes you will have to get that movie file, and you can change the name to anything.mkv and will search it by bytes.
