Suggestion: Add more constructors with parameters for JSONParserConfiguration

[Simulant87]

to me it was counter intuitive to create a default configured JSONParserConfiguration to then call withStrictMode() on it returning a clone and making the first instance obsolete. I would even need to create multiple clones until I have the correct configuration, when I want to set multiple values. I would like to be able to create my desired configuration in one go.

This would require a Constructor JSONParserConfiguration(boolean overwriteDuplicateKey, boolean strictMode) or even JSONParserConfiguration(boolean overwriteDuplicateKey, boolean strictMode, boolean keepStrings, int maxNestingDepth).

I would also allow the make the configuration fiels final although that would be a backwards compatible breaking change, and therefore will most probably not be added. I would make it reasier to reason about the codes behaviour and avoid the potential of changing an already used configuration.

What do you think of it?

@Simulant87 It is just the practice for configuration classes in this project. You will see similar APIs in JSONMLParserConfiguration and XMLParserConfiguration. Agreed it can be a bit inefficient, but it also has advantages. For example, XMLParserConfiguration has 6 tunable properties. I wouldn't want to be forced to init all of them when only one needs to be changed.
