[REQ] Allow quotes string as enum paramter names, or ensure unique names

Is your feature request related to a problem? Please describe.

using the typescript-fetch generator...

I am using Django Rest Framework to create my API. Its common practice to use an OrderingFilter to define fields and values that you specify to sort your results by.

order = OrderingFilter(
        fields=(
            ("id", "id"),
            ("name", "name"),
            ("status", "status"),
        )
    )

the api then will expect the following values:

Available values : -id, -name, -status, id, name, status

The typescript-fetch generator will generate the following enum in typescript:

export enum ListOrderEnum {
    Id = '-id',
    Name = '-name',
    Status = '-status',
    Id = 'id',
    Name = 'name',
    Status = 'status'
}

The minus sign is lost in the enum property names ( creating duplicate names ). I need to manually rename the property names. I use quotes to properly rename them, for example: '-Status' = '-status'

Describe the solution you'd like

Add an option that will allow the enum parameter name to be quoted strings, or that otherwise preserves the '-' in some other way.

Describe alternatives you've considered

something like 'ensureUniqueParams' but 'enumUniquePropertyNaming' that otherwise renames duplicate values. The '-' sign's signaling that this is a descending order parameter in the sort function might be lost, but at least my code would compile.

Additional context

Start by locating the typescript-fetch generator code that derives enum property names, then reproduce the issue with enum values such as -id and id from the reported Django REST Framework example. Done means generated TypeScript enum members are valid and unique while preserving the distinction between ascending and descending values, with regression coverage for the case.
