Add French language pack

[augnustin]

What a wonderful lib!

We are currently using it and it works very well!

The text we are currently indexing is in french. It seems like there is no dedicated language pack.

Let's start one?

Stopwords are easy to find:
Eg: https://github.com/explosion/spaCy/blob/master/spacy/lang/fr/stop_words.py

But for the stemmer, stripping a suffix from a dict is to simple of an heuristic (even the matcher isn't up to the task).
The code should accept a function instead of an object. Here are a couple of implementations of the Snowball French stemmer:

• https://github.com/bastienbot/nlp-js-tools-french/blob/master/algos/stem.js
• https://github.com/shibukawa/snowball-stemmer.jsx/blob/master/src/french-stemmer.jsx
• https://deno.land/x/[email protected]/french_stemmer.ts?s=FrenchStemmer

I hope this message finds you well. I am reaching out to see if anyone has experience or insights on how to integrate the French language into FlexSearch. I am currently exploring options and would appreciate any guidance or resources you might have.

Thank you in advance for your assistance.

A french language pack is now available in the new version: https://github.com/nextapps-de/flexsearch/blob/v0.8-preview/src/lang/fr.js
It needs to be completed.
