Release v5.0 · AppleCommander/bastools

What's Changed

As with AppleCommander, I am stepping away from semantic versioning. I don't know what release "0.x" means either!

Java 21 migration. If you are running the JAR files, please be certain that Java 21+ is being used.
Both bt and st are now being natively compiled for those who would prefer a native executable. Note that this is a tiny bit experimental, so please report any issues!
This ticket spawned a bunch of interesting things: Tokenizer manipulates leading and padding zeros on decimal numbers #49.
- Added classic and preserve token readers. Default is modern.
- Added proofreaders -
  - Compute! Apple Automatic Proofreader
  - Nibble: Apple Checker 3.0, Checkit
  - MicroSPARC: Key Perfect version 2.0, 4.0, and 5.0
  Example run:
```
$ bt --checkit checkit-example.bas 
Nibble Checkit, Copyright 1988, Microsparc Inc.
37|10 REM RING THE BELL
54|20  FOR J = 1 TO 5: PRINT  CHR$ (7): NEXT J
91|30  END 
TOTAL: 1CB9
```
- Note that the ticket is still open because I got distracted and there is a bit of work noodling on adding in the binary checkers as well.

Command-line test harness is now used to provide confidence that the compiled Java behaves like the Java bytecode. This is primarily due to Java being dynamic, sometimes -things- need to be done to be certain all the pieces are in place.
Repackaged from io.github.applecommander.bastools to org.applecommander. This will impact you if you are using the Java APIs in code.
TokenReader has been replaced with ModernTokenReader (originally TokenReader) and ClassicTokenRedaer.
General library updates.

Many thanks to @beheybird for the thoughts and discussion!
