v0.2.0

Changelog:

• Add Parser.of for memoization and apply it everywhere it makes sense;
• Add type parameter E to Parser base class for error types;
• Add type parameter C to Parser base class for context-passing types;
  • Make context handling transparent by introducing a new function runT that accepts a context and making run initialize it
    automatically;
  • Add context provider constructor parameter to Parser constructor for context initialization;
  • Implement TextContext with row and column for text parsers + index to avoid excessive substringing;
• Make all existing combinators consistent with the new error and context-passing types;
• Make ParserResult and context independent to make run's signature completely oblivious to the parsing context;
• Add tests to cover the text parsers;
  • Add CI pipelines for tests and coverage (+ badges! /o/).
• Minor refactoring on some arithmetic parsers to use zip instead of a nested map on a flatMap;
• Add pipeline to automatically bundle the plugin on releases;
