feat: allow no key transformations

[cquick01]

Allows the ability to define keys in JSON/dataclass that do not undergo transformation.

@dataclass
class MyDataclass(JSONWizard):
    VAR_1: int
    vAr__2: int
    VAr3__: int

    class _(JSONWizard.Meta):
        key_transform_with_dump = "NONE"

data = """{
    "VAR_1": 1,
    "vAr__2": 2,
    "VAr3__": 3
}
"""

foo = MyDataclass.from_json(data)
print("JSON -> Dataclass", foo)
print("Dataclass -> JSON", foo.to_json())

prints with no transformations

JSON -> Dataclass {
  "VAR_1": 1,
  "vAr__2": 2,
  "VAr3__": 3
}
Dataclass -> JSON {"VAR_1": 1, "vAr__2": 2, "VAr3__": 3}

hmm... just wondering... wouldn't lambda o: o be slightly more optimal here? assuming that we are loading from JSON, where all keys are a str anyway.

I don't have any problem with str() but it seems to just do unnecessary conversion when in 99% of cases, one could expect a key to be a str anyway. Let me know your thoughts @cquick01 .

That sounds reasonable, I'll push that change shortly. Thanks!

[cquick01]

Tested briefly with the example script in the PR, all seems to be working 👍

[rnag]

LGTM @cquick01 . I kicked off the CI workflow, will take a look and merge / deploy version later today if all seems good.

Closes #92 - just linking issue directly here.

@rnag Did this change get reversed? I see that NONE is not allowed :( and this code isn't in main? https://github.com/cquick01/dataclass-wizard/blob/main/dataclass_wizard/enums.py

[cquick01]

@adamcunnington-mlg I see it in main - https://github.com/rnag/dataclass-wizard/blob/main/dataclass_wizard/enums.py#L32

But I don't think a new tag/release was done

[adamcunnington-mlg]

@rnag please can you make a release?

[nathan-beam]

Bump @rnag - would like this feature. Thanks!

[rnag]

Sorry for the delay -- I just released v0.23.0 with the update to allow no key transformations.

Thanks for your work on this @cquick01 -- I credited you in the release notes.
