Offline spell checker for VSCode

Hello (first time contributing here) There are few offline spell checkers among VSCode extensions, but they are based on seriously faulty JavaScript implementations of [Hunspell](http://hunspell.github.io/) spell checker. [Hunspell](http://hunspell.github.io/) is nowadays probably the most widespread standard for spell check layer. It is used on MacOS, Linux and in some software (e.g. LibreOffice) on Windows. It is also used by both Atom and Sublime Text. There is an enormous collection of polished dictionaries for Hunspell. There exists some JavaScript implementations that refer to Hunspell's name but in fact they do not implement critical functionality - lexical parser. I have verified these three: [hunspell-spellchecker](https://github.com/GitbookIO/hunspell-spellchecker) [Typo.js](https://github.com/cfinke/Typo.js) [nspell](https://github.com/wooorm/nspell) All three work more or less following a simple idea of loading the dictionary into memory (into a associative table, a.k.a. dictionary, object to be precise).

When checking spelling dictionary is simply asked whether the word exist or not. Simple, but it has these implications: 1. Loading takes a lot of time; 2. It takes a lot of memory too; 3. Memory consumption causes them to crash under dictionaries with more expanded affix system (two out of three mentioned, th
