Improve performance, refactor NetexIdUtils

[skjolber]

• add lookup-table for char validation
• add null check for validator
• add more unit tests
• add simple JMH benchmark
• rewrite NetexIdUtils internals:
  • no more regexp
  • combine no.entur.abt.netex.id utils for the equivalent functionality

Benchmark results (higher is better - AMD 3700x)
