Feat: Add transformer option to use-query

Overview

I've added a transformer option to use-query. This allows you to transform data, such as converting from snake_case to camelCase.

CODE: snakeToCamel function

import camelcaseKeys from "camelcase-keys";

export type SnakeToCamelCase<S extends string> =
  S extends `${infer T}_${infer U}`
    ? `${Lowercase<T>}${Capitalize<SnakeToCamelCase<U>>}`
    : S;
export type SnakeToCamelCaseNested<T> = T extends (infer U)[]
  ? SnakeToCamelCaseNested<U>[]
  : T extends object
    ? {
        [K in keyof T as SnakeToCamelCase<K & string>]: SnakeToCamelCaseNested<
          T[K]
        >;
      }
    : T;

export const snakeToCamel = <
  T extends Record<string, unknown> | readonly Record<string, unknown>[],
>(
  request: T
) => camelcaseKeys(request) as unknown as SnakeToCamelCaseNested<T>;

Additional Notes

I'm a junior engineer. This is my first contribution to an open-source project. I'm eager to receive feedback on my work. I'm very interested in Supabase and would love to work on other issues if there are any.
