Make the safe-string-interpolation faster

[plokhotnyuk]

Would you consider to serialize faster and with less allocations?

I have a couple of projects that have routines or tricks which can be reused here:

1. fast-string-interpolator that uses pre-allocated thread local instances of java.lang.StringBuilder under hood.
2. jsoniter-scala that has very efficient routines for serialization of double or float primitives, java.util.UUID, and java.time.* classes.

This is a great input. Thanks for that. I will be interested in these projects. I am planning for a release before the end of this year. Let’s work on it

Here are small but more efficient than standard implementations of .toString for java.time._ types.
