v22.0.0

Additions

• ResourcePool for reusable resources (resource-per thread, fixed- and variable-sized pools).

Breaking Changes

• removed deprecated overloads of LangUtil.check(), LangUtil.checkArg(), and LangUtil.require...()
  methods.
• removed LangUtil.wrapException(), use `LangUtil.throwAsRuntimeException instead.
• removed the Counter class; use java.util.concurrent.atomic.LongAdder instead, it's standard and it's faster.
• LangUtil.uncheckedConsumer(), LangUtil.uncheckedFunction(), LangUtil.uncheckedSupplier(), and
  LangUtil.uncheckedRunnable() have been replaced by LangUtil.unchecked(); overloads have been
  implemented that cover the use cases Supplier, (Bi)Consumer, (Bi)Function, and Runnable.

Bugfixes

Other Changes

• RichTextBuilder: performance optimization.
• FxLauncher: command line option to set log level.
• Some small fixes and improvements; reduce code duplication.
