Replace sqflint with @bi-tools

[SkaceKamen]

@bi-tools is set of libraries to interact with Arma-related files made by me implemented in typescript. The primary goal of the libraries is to support this extension.

Goals:

• get rid of Java dependency
• improve parsing to support all SQF constructs (sqflint is a bit limited right now)
• improve preprocessor to support all macros and commands
• separate parsing, linting and analysis into their own modules:
  • parser - only generates AST
  • linter - generates warnings based on AST
  • analyser - builds info used by extension, such as variable list, etc
• improve configuratibility
• possibly introduce refactoring utilities
• refactor the language server code a bit, it's a mess currently

State:

• [x] implement pre-processor
• [x] implement fully featured SQF parser
• [x] implement basic SQF analyzer (just variables now)
• [x] implement basic SQF linter
• [x] integrate preprocessor, SQF parser and analyzer into extension
• [ ] ANALYZER: implement context-based variables checker
• [ ] LINTER: implement more complex rules
• [x] PARSER: improve error reporting
• [x] PARSER: implement error recovery
• [x] PREPROCESSOR: fix source maps
• [ ] integrate linter with extension
• [ ] properly integrate errors with extension (accepting errors from different files when parsing a single file)
