Change custom stripping leading and trailing whitespaces implementation
to substantially improves performance:
```
Benchmark                         Mode  Cnt      Score     Error  Units
StringTrim.testWithStringBuilder  avgt   25  82547.575 ±  66.244  ns/op (existing impl)
StringTrim.testWithSubstring      avgt   25   1398.762 ± 101.152  ns/op (new impl)
StringTrim.testWithJavaStrip      avgt   25   1186.120 ±  10.374  ns/op (for reference)
```
Java's string stripLeading()/stripTrailing() not available to all supported JDKs.
