Support for legacy enum

[mlankamp]

Describe the problem

When upgrading from openapi-typescript-codegen the handling of enum is totally different and based on the thread #60 I understand why. But this causes so large upgrade issues in our code base.

Describe the proposed solution

It would be nice to have an --useLegacyEnum flag which would use the typescript enum construct.

Hey @mlankamp, how many errors are we talking about? Are you able to use this approach to migrate your code? https://github.com/hey-api/openapi-ts?tab=readme-ov-file#useoptions-true

[mlankamp]

I think we have like 100+ different enums in our code, and because the models are different between the new and old this doesn't allow us to upgrade easily

@mlankamp I have released this in version 0.29.0 of @hey-api/openapi-ts.

[mlankamp]

Thanks, I need to update 1 thing. The index.ts writes the enums as export type {} from ... where the type should be removed. Will send an update later today

[jordanshatford]

@mlankamp no need. I have made the fix #158 and will release as 0.29.1 shortly

[jordanshatford]

I have just released the version with the fix.

[mlankamp]

I think the fix is to aggressive, nothing is export as type anymore. I created a solution also, which only targets the enums

[jordanshatford]

@mlankamp I have merged your change and will be releaseing 0.29.2 shortly
