jsloccount 2.0.0

Modernized for Java 21, with the counting and reporting defects that
predated it fixed and coverage grown from 83 file types to 192.

Reports

• the two CSV columns were crossed: -filestats.csv carried line counts
  under "File Count" and -sizestats.csv carried file counts under "Source
  Lines of Code"
• fields are escaped per RFC 4180
• binary resources no longer pad the size report with zeroes

Counting

• multi-line block comments were counted as code beyond their opening line,
  and an inline /* */ counted its line as source twice
• comment markers inside string literals opened comments, so a line holding
  "http://example.com" was reported as a comment
• block comments nest where the language nests them: Rust, Swift, Scala,
  Kotlin, Dart, Haskell, OCaml, F#, Julia, and D's /+ +/
• Fortran's marker matched nothing in any dialect; Haskell, Pascal and
  batch files were missing forms of theirs
• Vim Script's " is read as a comment or a string by position and by
  whether it closes, rather than always as a comment
• Lua long brackets are recognized at levels [[ through [===[

Interface

• -o, -n, --stdout, -x, --include-hidden, -q, --list-languages, -h, -V
• logging moved to standard error, so --stdout carries clean CSV
• exit 0 on success, 1 for an unscannable directory, 2 for misuse

Coverage

• 192 file types, text and binary, from 83
• the most common unrecognized suffixes are reported after a scan

Documentation

• the supported types are grouped into ten categories, derived from the enum
  so the list cannot drift, and printed the same way by --list-languages

Requires Java 21 or newer.
