Added a GraalVM launcher for HeadlessMc

• Added Java downloading capabilities (extensible, Temurin distribution only for now).
  • Had to add a large dependency on apache-commons-compress for tars
• Pulled headlessmc-os and headlessmc-java out of the launcher (was not necessary in the end, because the graalvm module still depends on the launcher, but they make for good standalone-libraries)
• Added a GraalVM launcher for HeadlessMc:
  • It simply runs the headlessmc-launcher-wrapper with a java executable it finds/downloads.
  • This approach has been chosen for three reasons:
    • Plugin support with GraalVM is challenging, potentially resolvable with Truffle?
    • In-memory launching is also problematic in the same way.
    • Current instrumentation loads classes to determine common superclasses for ASM.
      • It's a wonder this has not blown up yet: Imagine loading a class for a newer JVM version. Also, I do not think this actually loads the entire classpath, but just the jar, so it would also fail if the common superclass is in another jar. There's scope for developing an ASM-only analyzer to scan JAR files for common superclasses without loading them. This is noted as TODO for future improvement.
• Bumped the project version to 2.5.0

This is a lot to go through, next time multiple commits, please.

Awesome stuff, with some nitpicks. I think you can ignore codacy for now, I will clean this up a bit later.

[3arthqu4ke]

And lots of failed tests?

[3arthqu4ke]

Thanks, will improve some of the code, add 1-2 features and release soon.

Codacy seems to have a problem and can be ignored for now.
