feat: adding possibility to pass an object as parameter to customLevels

[ademarsj]

Hello, i made the changes to make possible pass in code as object or string the customLevels prop, it's still compatible with the CLI passing as string parameter. I already wrote the tests too and keeps on the 100% coverage and asserted.

Is relative to #399 .

I appreciate the request and comments, i fixed them, but i got some doubts/points:

• I believe that you just give me an example of the method docs, so i changed a little to something more strict to the function returns
• I noticed that in handleCustomlevelNamesOpts method when passing an object as parameter the return is practically the same object that is passed, but i didn't remove the logic because of the lower case transformation, do you think it's appropriate to leave it that way ? Or just return the object as it came (expecting that the user will always pass an object with properties names already in lower case), and pass to lower case only in string mode ?
• I added the docs to the PrettyOptions with examples, I hope I made right

I would review the git blame for the implementation and the PRs that introduced it. The discussion therein should answer these questions.

I don't understand. What is PrettyOptions?

I did it, in this PR, as it was just passed as a string it always will transform to lower case to make the attributes names to the object returned, now it will receive an object, if the object received it's already with lower case in his attributes names the for loop is useless, once it will return an object same as received.

I don't understand. What is PrettyOptions? The name of the Interface in index.d.ts which describes the pino-pretty options.

I will fix the English errors that you appointed soon.

Done, sorry for the bad english.

No worries. That's what reviews are for.
