How about support encoding or decoding for key ?

[lu911]

[REQUIRED] Step 1: Describe your environment

• Xcode version: 10.1
• Pring version: 0.14.0

[REQUIRED] Step 3: Describe the problem

Steps to reproduce:

I declared variable as camel-case in model. But I have to save using underscore to firestore.
I found encoding or decoding for value but couldn't change for key. I try to change _properties but it's private variable.

How about support decodeKey, encodeKey ?

Relevant Code:

// TODO(you): code here to reproduce the problem

You can override ModelName.

@1amageek I think it's better to add a feature and I will send PR when I have it done. How is it sound?
